The original version of the article contained an erroneously assigned topology for cocrystal (HACA)2(4,4′-azpy) (2) (HACA = α-acetamidocinnamic acid, 4,4′-azpy = 4,4′-azopyridine) when their molecules were considered as nodes. This affected the structural description of cocrystal 2 (page 1754) and its corresponding figure (Figure 5, page 1756), as well as the X-ray crystallographic data, which was updated with the last version of the ToposPro program and the TopCryst webpage (page 1749). In addition, the acknowledgments were modified after a helpful discussion with Prof. Davide M. Proserpio which led us to realize the mistakes corrected herein (page 1762). The corrections of the article are shown below.
Figure 5.
Schematic representation of the topologies of cocrystals 1 and 2 considering (a) their former molecules (HACA and dPy) and (b) their BSMs as nodes. The 4,4′-azpy molecules from cocrystal 2 have been simplified in panel (a) due to the obtention of 2-c nodes which should be removed according to the methodology of reference 52 of the original paper.
X-ray Crystallographic Data.
The topological analysis was done employing the ToposPro 5.5.2.1 program and the TopCryst Web site (https://www.topcryst.com/).
Structural Description of (HACA)2(1,2-bpe) (1) and (HACA)2(4,4′-azpy) (2).
Otherwise, the C(8)–H(2)···O(1) (2.56 Å, 132°) interaction in cocrystal 2 extended its 3D network forming a 5-c sqp underlying topology, sustained by azo···π interactions (Cg(1)···Cg(2): 3.648 Å)70 (Table 5, Figures 4c,d and 5a), being in agreement with the flat regions of the HACA and 4,4′-azpy regions in their corresponding curvedness representations (SI FigureS20b,e).
