A hydrogen-bond bridged layer host: crystal structure of 2-phenylethylammonium tetracyanonickelate(II)-(N,N-dimethylaniline)(1/1)
Abstract
The ammonio group of 2-phenylethylammonium cation links tetracyanonickelate(II) anions at the N atoms of square-planar Ni(CN)4 moieties through hydrogen bonds to form a layer of doubly-CN-bridged one dimensional extensions of [(PhCH2CH2NH3)2Ni(CN)4]n with protrusion of the 2-phenylethyl groups into the interlayer space; these groups act as the spacers to produce the cavities for the guest N,N-dimethylaniline molecules.
