Poly[(5,5′-dimethyl-2,2′-bipyridine-κ²N,N′)(μ₃-5-hydroxyisophthalato-κ⁴O¹:O³,O^3′:O^3′)cadmium]

Abstract

In the title compound, [Cd(C8H4O5)(C12H12N2)], the CdII cation is coordinated by three 5-hy­droxy­isophthalate anions and one 5,5′-bimethyl-2,2′-bipyridine ligand in a distorted CdO4N2 octa­hedral geometry. The 5-hy­droxy­isophthalate anions bridge the Cd cations, forming a two-dimensional polymeric complex parallel to (100). In the complex, the hy­droxy group is linked to the uncoordinated carb­oxy-O atom via an O—H⋯O hydrogen bond. Weak C—H⋯O hydrogen bonds are also present in the crystal structure. One of the methyl groups is disordered over two positions in a 0.536 (11):0.464 (11) ratio.
