Bis(μ-N,N′-di-4-pyridylpyridine-2,6-diamine)bis[dimethacrylatocobalt(II)] dihydrate

Abstract

Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.004 Å; disorder in main residue; R factor = 0.036; wR factor = 0.113; data-to-parameter ratio = 13.4.The Co II ion in the title complex, [Co 2 (C 4 H 5 O 2 ) 4 (C 15 H 13 -N 5 ) 2 ]Á2H 2 O, has a distorted square-planar coordination formed by the bridging bidentate N,N 0 -di-4-pyridylpyridine-2,6-diamine (dapmp) ligands and two monodentate carboxylate groups from methacrylates. Two dapmp ligands bridge two Co atoms, forming a dinuclear complex arranged around an inversion centre. N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds involving the solvent water molecule result in the formation of a three-dimensional network. The aliphatic moiety of one of the methacrylate groups is disordered over two positions with fixed occupancies of 0.67 and 0.33. Related literature
