Abstract

Reaction of cadmium nitrate with diphenylphosphinic acid in dimethylformamide solvent yielded the one-dimensional coordination polymer catena-poly[[bis(dimethylformamide-κO)cadmium(II)]-bis(μ-diphenylphosphinato-κ2 O:O′)], [Cd(C12H10O2P)2(C3H7NO)2] n , (I). Addition of 4,4′-bipyridine to the synthesis afforded a two-dimensional extended structure, poly[[(μ-4,4′-bipyridine-κ2 N:N′)bis(μ-diphenylphosphinato-κ2 O:O′)cadmium(II)] dimethylformamide monosolvate], {[Cd(C12H10O2P)2(C10H8N2)].C3H7NO} n , (II). In (II), the 4,4′-bipyridine molecules link the CdII centers in the crystallographic a direction, while the phosphinate ligands link the CdII centers in the crystallographic b direction to complete a two-dimensional sheet structure. Consideration of additional π-π interactions of the phenyl rings in (II) produces a three-dimensional structure with channels that encapsulate dimethylformamide molecules as solvent of crystallization. Both compounds were characterized by single-crystal X-ray diffraction and FT-IR analysis.
