Dihydro­nium hexa­kis[bromido/chlorido(0.75/0.25)]dicadmate(II)–triphenyl­phosphine oxide (1/6)

Abstract

In the salt, (H₃O)₂[Cd₂Br_4.5Cl_1.5]·6C₁₈H₁₅OP, the hydro­nium cation forms short O—H⋯O hydrogen bonds to the O atoms of the triphenyl­phosphine oxide units. The centrosymmetric dinuclear anion has two halide atoms functioning in a bridging mode, which confers tetra­hedral coordination to the Cd atom. The three independent halide atoms are each a mixture of bromide and chloride; the occupancies of the Br atoms are 0.6434 (11), 0.7468 (11) and 0.8598 (11).

Experimental

Cadmium chloride dihydrate (0.22 g, 1 mmol) was dissolved in water (10 ml); triphenylphosphine dibromide (0.8 g, 2 mmol) was dissolved in ethanol (90 ml). The two solutions were mixed and then heated for 1 h. Slow evaporation of the filtrate gave colorless, irregularly-shaped crystals.

Refinement

Hydrogen atoms were placed at calculated positions (C–H 0.95 Å) and were treated as riding on their parent atoms, with U(H) set to 1.2U_eq(C). The acid H-atoms were located in a difference Fourier map, and were refined with a distance restraint of O–H 0.84±0.01 Å; their isotropic temperature factors were refined.

The three independent halogen atoms are each a mixture of bromide and chloride atoms. The total bromide occupancy refined to nearly 2.25; this was then set as exactly 2.25. The occupancies of the Br1, Br2 and Br3 atoms are 0.6434 (11), 0.7468 (11) and 0.8598 (11).

Special details

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