Crystal structure of di-μ-chlorido-bis[dichlorido(L-histidinium-κO)cadmium(II)]

Abstract

In the title compound, [Cd2(C6H9N3O2)2Cl6], the coordination polyhedra around the CdII cations are distorted trigonal bipyramids. Two of the chloride ions (one axial and one equatorial) are bridging to the other metal atom, leading to a Cd...Cd separation of 3.9162 (4) Å. The O atom of the L-histidinium cation lies in an axial site. In the crystal, numerous N—H...Cl, N—H...O, C—H...O and C—H...Cl hydrogen bonds link the molecules into a three-dimensional network. Theoretical calculations and spectroscopic data are available as supporting information.
