In this work, we report the synthesis and X-ray characterization of diphenylphosphinic acid (L) and its two polymeric phosphinate complexes, [(C6H5)2P(O)OSn(C6H5)3]n (C1) and [Cu(O2PPh2)2]n (C2), resulted from the bidentate coordinatioan of L. Sn(IV) centers in C1 are five-coordinate in a distorted trigonal bipyramidal geometry. One dimensional coordination chains of C2 are made by double-bridging ligands between the copper atoms, surrounded with four P-O in a square planar polyhedron. Structural characterization of the complexes revealed that M-O bonds are responsible for the assembly of the pri mary structural motifs in both the complexes while C-H … p and H/H interactions are effective in organizing these molecules into extended 3D architectures. The quantitative mapping of interactions was also analyzed using Hirshfeld surface analysis.
