Bis(μ-1,2-bis{[2-(2-pyridyl)-1H-imidazol-1-yl]methyl}benzene)bis[bis(thiocyanato-κN)cadmium(II)]
The asymmetric unit of the binuclear title compound, [Cd(2)(NCS)(4)(C(24)H(20)N(6))(2)], contains one half-molecule, consisting of one Cd(2+) cation, two half 1,2-bis{[2-(2-pyridyl)-1H-imidazol-1-yl]methyl}benzene (L) ligands and two SCN(−) anions. The dimeric cyclic molecule is completed by cr...

Sumario: | The asymmetric unit of the binuclear title compound, [Cd(2)(NCS)(4)(C(24)H(20)N(6))(2)], contains one half-molecule, consisting of one Cd(2+) cation, two half 1,2-bis{[2-(2-pyridyl)-1H-imidazol-1-yl]methyl}benzene (L) ligands and two SCN(−) anions. The dimeric cyclic molecule is completed by crystallographic inversion symmetry. The Cd(2+) cation is coordinated by two N atoms from two SCN(−) anions and four N atoms from two symmetry-related L ligands, exhibiting a distorted octrahedral coordination. A two-dimensional supramolecular network stacked parallel to [210] is finally formed by linking these dimers through weak π–π stacking interactions between the pyridine rings and benzene rings of adjacent dimers, with a plane-to-plane distance of 3.36 (6) Å and a centroid–centroid distance of 3.67 (2) Å. One of the thiocyanate S atoms is equally disordered over two positions. |
