Synthesis, characterization and crystal structure of the bimetallic cyano-bridged [(η5-C5H5)(PPh3)2Ru(μ-CN)Ru(PPh3)2(η5-C5H5)][PF6]
摘要:
The bimetallic cyano-bridged [(eta(5) -C5H5)(PPh3)(2)Ru(mu-CN)Ru(PPh3)(2)(eta(5)-C5H5)][PF6] (1) was prepared by reaction of [(eta(5)-C5H5)(PPh3)(2)RuCl] with NN '-bis(cyanomethyl)ethylenediamine. The single crystal structure determined by X-ray diffraction showed crystallization on the triclinic PI space group with a perfect alignment of the cyanide bridges. This accentric crystallization was explored having in view the NLO properties at the macroscopic level, determined by the Kurtz Powder technique. Besides the very low efficiency values for the second harmonic generation, the value obtained for the bimetallic complex I showed to be higher than one of the parent complex [(eta(5)-C5H5)(PPh3)(2)RuCN] (2).
