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(1i) anions at the N atoms of square-planar Ni(CN)4 moieties through hydrogen bonds to form a layer of dou bly-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.

Synthesis and Structure of a Two-Dimensional Cyano-Bridged Coordination Polymer [Cu(cyclam)]2[Mo(CN)8]·10.5H2O (Cyclam = 1,4,8,11-Tetraazacyclodecane)

“…In contrast, heptacyanometalate building blocks, which are potentially incompatible with symmetrical lattices, gives rise to very anisotropic networks with an unusual topology . The more creative approach to the design of cyano-bridged coordination polymers has been to use metal complexes with complementary capping ligands such as NH 3 , , aliphatic 1 and aromatic amines, ,,7a,8a ambidentate diaminoalkanes , ,7b,9b bipyridine,14e etc... These ligands play an important role in stabilizing the multidimensional structures and impose a specific network topology through their geometries and coordination binding modes.…”
