Bis(μ-N,N′-di-4-pyridylpyridine-2,6-diamine)bis[dimethacrylatocobalt(II)] dihydrate
Abstract
The CoII ion in the title complex, [Co2(C4H5O2)4(C15H13N5)2]·2H2O, has a distorted square-planar coordination formed by the bridging bidentate N,N′-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—H...O and O—H...O 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.
