Crystal structures and non-linear optics of several types of bimetallic assemblies comprising chiral Cu(II) complexes

We have synthesized various chiral bimetallic assemblies, [CuL2][Ni(CN)4]·2H2O, [CuL2]3[Co(CN)6]2·5H2O·4DMSO, [CuL2]2[Fe(CN)6]·10H2O, [CuL2]2[CrO4]2·5H2O, and [CuL2]2[MoO4]2·3H2O·2DMSO (L = (1R,2R)-diphenylethylenediamine), and discussed their crystal structures, spectroscopic, magnetic properties and non-linear optical properties. Except for one-dimensional hydrogen bonding [CuL2][Ni(CN)4]·2H2O (P1 space group), which exhibits one-dimensional hydrogen bonding, four materials exhibit NLO properties.106
