نویسندگان
چکیده
The title cobalt(II) complex, [CoCl(2)(C(3)H(6)N(4)O)(4)], was obtained from metallic cobalt by direct synthesis. There are two Co atoms in the asymmetric unit, each lying on an inversion centre and adopting a distorted octa-hedral coordination. Classical and non-classical hydrogen bonds are responsible for formation of a three-dimensional polymeric network in the crystal.

In the title compound, [Co(C(10)H(7)N(2)O(2))(2)(H(2)O)(4)], the Co(II) atom lies on an inversion centre and displays a slightly distorted octa-hedral geometry. The coordination sphere is defined by two mutually trans N atoms from two 4-(imidazol-1-yl)benzoate ligands and the O atoms from four water mol-ecules. The crystal structure is stabilized by O-H⋯O hydrogen bonds.
