CRYSTAL STRUCTURE OF HOFMANN-DMA-TYPE BENZENE CLATHRATE BIS(DIMETHYLAMINE)CADMIUM(II) TETRACYANONICKELATE(II)-BENZENE (2/1)

Abstract
The title clathrate Cd(NH(CH3)2)2Ni(CN)4·\frac12C6H6 has a layered host structure of metal complex network [CdNi(CN)4]∞ linked by the CN ligands and the benzene molecule is enclathrated in a cage-like cavity formed between the layers. The channel-like cavity, observed along with the cage-like one for the Hofmann-dma-type toluidine clathrates, is collapsed owing to the fold of the layers to minimize void space.
