A new three-dimensional anionic cadmium(II) dicyanamide network

In a new cadmium dicyanamide complex, poly[tetra­methyl­phospho­nium [μ-chlorido-di-μ-dicyanamido-cadmium(II)]], each Cd^II atom is octa­hedrally coordinated by four terminal N atoms from four anionic dicyanamide ligands and by two chloride ligands. The dicyanamide ligands play two different roles in the building up of the structure. The anionic framework exhibits a solvent-accessible void of 673.8 ų, which is 47.44% of the total unit-cell volume. The cavities are occupied by pairs of tetra­methyl­phospho­nium cations.

One- and two-dimensional Cd^II coordination polymers constructed from 2-(2-methyl-1H-benzimidazol-1-yl)acetate ligands

The one- and two-dimensional polymorphic cadmium polycarboxyl­ate coordination polymers catena-poly[bis[[mu]₂-2-(2-methyl-1H-benzimidazol-1-yl)acetato]cadmium(II)] and poly[bis[[mu]₂-2-(2-methyl-1H-benzimidazol-1-yl)acetato]cadmium(II)] were prepared under similar solvothermal conditions. Alternating layers of chains in the former are perpendicular to one another, while the latter contains (4,4)-connected nodes yielding square-grid layers.
