Triaqua(7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylato-κ3 O 2,O 3,O 7)cobalt(II) monohydrate

چکیده
The title complex, [Co(C(8)H(8)O(5))(H(2)O)(3)]·H(2)O, was synthesized by reaction of cobalt acetate with 7-oxabicyclo-[2.2.1]heptane-2,3-dicarb-oxy-lic anhydride (norcantharidin) in aqueous solution. In the mol-ecule, the Co(II) atom is six-coordinated in a distorted octa-hedral environment, binding to the bridging O atom of the bicyclo-heptane unit, to two O atoms from monodentate carboxyl-ate groups and to three water O atoms. The crystal structure is stabilized by several O-H⋯O hydrogen-bonding inter-actions involving both the coordinated and uncoordinated water mol-ecules as donors and the carboxyl-ate O atoms of neighbouring mol-ecules as acceptors.

In the crystal structure of the title compound, [Co(C(8)H(8)O(5))(C(3)H(4)N(2))(3)]·3.35H(2)O, the central Co(II) ion is in a slightly distorted octa-hedral environment, coordinated by the bridg-ing O atom from the bicyclo-[2.2.1]heptane ligand, by two carboxyl-ate O atoms from two different carboxyl-ate groups and by three N atoms from imidazole ligands. Uncoordinated water mol-ecules, some of...
