Abstract
In the title compound, [Cd4Cl8(C6H16N2)4], the Cd2+ cations and Cl− anions form M 4Cl8 clusters with six of the Cl− ions bridging Cd2+ cations and two being pendant. Each Cd2+ cation has distorted octahedral coordination completed by four Cl− ions and two N atoms of the asymmetrical bidentate amino ligand. The cluster consists of pairs of face-sharing hexahedra linked by a shared edge.
Highlights
The coordination chemistry of cadmium is of interest to a wide range of disciplines ranging from toxicology to catalysis (Melnik et al, 2009; Andersen et al, 1984)
Each complex unit has four amino ligands with two nitrogen atoms of each ligand coordinating to one Cd2+ ion (Fig. 1)
Each Cd2+ cation has a distorted octahedral coordination completed by four ClÀ ions and two nitrogen atoms of the bidentate amino ligand
Summary
The coordination chemistry of cadmium is of interest to a wide range of disciplines ranging from toxicology to catalysis (Melnik et al, 2009; Andersen et al, 1984). Each complex unit has four amino ligands with two nitrogen atoms of each ligand coordinating to one Cd2+ ion (Fig. 1). CdÁ Á ÁCl distances range from 2.5158 (19) to 2.8227 (18) Ain the cluster. Each Cd2+ cation has a distorted octahedral coordination completed by four ClÀ ions and two nitrogen atoms of the bidentate amino ligand. The cluster consists of pairs of face-sharing hexahedra linked by a shared edge. The complex units are linked by intermolecular N— HÁ Á ÁCl contacts with NÁ Á ÁCl distances in the range 3.407 (6) to 3.548 (6) Aand N— HÁ Á ÁCl angles in the range 140.5 to 146.3 (Fig. 2, Table 1). Each complex unit donates four and accepts four N—HÁ Á ÁCl contacts with each pendant ClÀ accepting two bonds from different units
