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

The Co(II) ion in the title complex, [Co(2)(C(4)H(5)O(2))(4)(C(15)H(13)N(5))(2)]·2H(2)O, has a distorted square-planar coordination formed by the bridging bidentate N,N'-di-4-pyridylpyrid-ine-2,6-diamine (dapmp) ligands and two monodentate carboxyl-ate 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 mol-ecule 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.
