Crystal structure of an organic–inorganic hybrid compound based on morpholinium cations and a β-type Anderson polyanion

The crystal structure of the novel organic–inorganic hybrid compound is based on a β-type Anderson polyoxidomolybdate anion containing a central Fe^III ion. In the crystal, inter­molecular N—H⋯O and O—H⋯O hydrogen bonds link the components into a three-dimensional network structure.

Abstract

A new organic–inorganic hybrid compound, penta­morpholinium hexa­hydrogen hexa­molybdoferrate(III) sulfate 3.5-hydrate, (C₄H₁₀NO)₅[Fe^III(OH)₆Mo₆O₁₈](SO₄)·3.5H₂O, was obtained from an aqueous solution. The polyoxidomolybdate (POM) anion is of the Anderson β-type with a central Fe^III ion. Three of five crystallographically independent morpholinium cations are disordered over two sets of sites. An intricate network of inter­molecular N—H⋯O and O—H⋯O inter­actions between cations, POMs, sulfate anions and non-coordinating water mol­ecules creates a three-dimensional network structure.

Chemical context  

Polyoxidometalates (POM) are attractive mol­ecular building blocks used in the formation of multidimensional organic–inorganic hybrid networks during self-organization processes (Pope & Müller, 2001 ▸; Müller et al., 1998 ▸; Long et al., 2007 ▸). POMs play an important role in the design of new classes of functionalized materials not only because of their topological versatility and high dimensional architectures, but also due to their rich diversity of remarkable properties. Several related compounds with Anderson-type polyoxidometalate anions and organic cations, such as (C₄H₁₂N₂)₅[Al(OH)₆Mo₆O₁₈]₂(SO₄)₂·16H₂O (Yang et al., 2009 ▸), (C₄H₁₀NO)₃[Cr(OH)₆Mo₆O₁₈]·4H₂O (Yang et al., 2011 ▸), (C₆H₁₀N₃O₂)₂Na(H₂O)₂[Al(OH)₆Mo₆O₁₈]·6H₂O (Thabet et al., 2012 ▸) and other compounds with an Fe^III central ion (Marcoux et al., 2003 ▸; Allain et al., 2008 ▸; Dessapt et al., 2011 ▸) have been reported. In β-type Anderson polyoxidoanions, which are characterized by a planar arrangement of the metal atoms, each Mo^VI atom has two terminal oxygen atoms, two bridging O atoms and two bridging OH functions which make it highly reactive and easily coordinated by varieties of transition metal atoms in the anion.

Here we report synthesis and structure of the new organic–inorganic hybrid compound (C₄H₁₀NO)₅[Fe^III(OH)₆Mo₆O₁₈](SO₄)·3.5H₂O, (I).

Structural commentary  

The asymmetric unit of compound (I) is made up of one Anderson β-type polyoxidoanion, [Fe(OH)₆Mo₆O₁₈]³⁻, abbreviated in the following as {FeMo₆}, five morpholinium cations (C₄H₁₀NO)⁺, one sulfate anion and four non-coordinating water mol­ecules (Fig. 1 ▸). Three of the morpholinium cations are disordered over two sets of sites and one water mol­ecule (O1W) shows half-occupancy. The {FeMo₆} anion is formed by six edge-sharing [MoO₆] octa­hedra, which are arranged hexa­gonally around the central [Fe(OH)₆] octa­hedron with bond lengths and angles that are within the expected ranges for this type of POM anion (Cao et al., 2007 ▸). The six hydroxyl groups of the Anderson-type polyoxoanion are involved as donor groups in hydrogen-bond formation with O atoms of the sulfate anions and the non-coordinating water mol­ecules.

Supra­molecular features  

In the crystal structure of compound (I), hydrogen-bonding inter­actions between morpholinium cations, polyoxidoanions, sulfate anions and non-coordinating water mol­ecules are of the types O—H⋯O and N—H⋯O (Table 1 ▸) and connect the discrete units into a three-dimensional supra­molecular network. Hydrogen bonding is the dominating inter­molecular inter­action involved in the construction of this architecture and gives sufficient stabilization of its crystal structure. Figs. 2 ▸ and 3 ▸ shows the crystal packing with hydrogen-bonding inter­actions.

Synthesis and crystallization  

The title compound was synthesized by the following procedure: 0.320 g (0.8 mmol) of iron(III) sulfate was dissolved in 10 ml of double-distilled water. To this solution 4 ml (5 mmol) of morpholine and 0.309 g (1.5 mmol) of Na₂MoO₄ were added during constant stirring. By the addition of 30%_wt sulfuric acid, the pH was adjusted to 2.5. The resultant solution was filtered and the filtrate kept at room temperature. After few weeks, light-brown crystals were obtained.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. Three of the five crystallographically independent morpholinium cations are disordered, for which all atoms are distributed between two positions. The refined site occupation factor ratios are as follows: 0.857 (6):0.143 (6), 0.703 (9):0.297 (9) and 0.857 (6):0.143 (6) for O1C–C6C/O11C–C61C, O1D–C6D/O11D–C61D and O1E–C6E/O11E–C61E, respectively. All non-hydrogen atoms were refined anisotropically, except for the minor parts of the disordered morpholinium cations. The positions of the H atoms were initially located in difference Fourier maps. All H atoms were fixed at ideal positions, with U _iso(H) = 1.2U _eq of the parent atom (1.5U _eq for water H atoms). In the final refinement cycles, H atoms of the O1W water mol­ecule were allowed to ride on the parent O atom (AFIX 3 in SHELXL2014; Sheldrick, 2015 ▸), H atoms of the other water mol­ecules were fixed with the AFIX 6 instruction. For the minor component of disorder for morpholinium cation (O11C > C61C) the SAME instruction was used. Pairs of morpho­lin­ium cations (labelled C and E) were initially refined with individual occupation factor variables which turned out to refine to the same value (taking into account standard uncertainties). As a result of the fact that disordered parts of these two cations are connected by hydrogen-bonding inter­actions, disorder was restrained with a common occupation factor variable in the final refinement. One of the O atom of a water mol­ecule (O1W) is characterized by a significantly elongated displacement parameter. The occupation factor of this mol­ecule was arbitrarily fixed at 50%.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
