Abstract:
The title compound, {[Co(C(2)H(5)COO)(2)(H(2)O)]·H(2)O}(n), was synthesized by the reaction of cobalt(II) carbonate hydrate with aqueous propionic acid. The structure consists of polymeric infinite linear chains with composition [Co(C(2)H(5)COO)(4/2)(H(2)O)(2/2)](∞) running along [010]. The chains are formed by Co(2+) ions linked with bridging propionate groups and water mol-ecules, with a Co⋯Co distance along the chains of 3.2587 (9) Å. The Co(2+) ion is six-coordinated in a strongly distorted octa-hedral geometry. The chains are connected to each other by a network of O-H⋯O hydrogen bonds involving solvent water mol-ecules.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
