Abstract

Abstract Cubic molecular optical non-linearities of a systematically varied series of octahedral bis{bis(diphenylphosphino)methane}ruthenium σ-acetylide complexes have been determined by the Z-scan technique: the influence on the non-linear response of sequential replacement of chloro by acetylide ligand in trans-[RuCl 2(dppm) 2] and acetylide chain length in proceeding from 4-nitrophenyl- to 4-nitrobiphenyl- and 4-nitro-( E)-stilbenylacetylide has been studied. The first X-ray structuralstudy of an unsymmetrical bis(acetylide) complex of this type, trans-[Ru(CCPh)(4-CCC 6H 4NO 2)(dppm) 2], is reported and confirms the trans-diposed stereochemistry of the alkynyl ligands.
