%X The complexes &#91;Au(4-C&#197;&#8801;CC6F4OMe)(L)&#93; &#91;L = PMe3 (1), PPh3 (2)&#93;,trans-&#91;Ru(4-C=CHC6F4OMe)Cl(dppm)2&#93;PF6(3) and trans-&#91;Ru(4-C&#197;&#8801;CC6F4OMe)Cl(dppm)2&#93;(4) have been prepared and the identity of (2) was confirmed by a structural study. Electrochemical data for (3) and (4) suggest that the 4-C6F4OMe group lies midway between Ph and 4-C6H4NO2in electron-withdrawing strength. Quadratic non-linearities at 1064 nm, determined by the hyper-Rayleigh scattering technique, increase for co-ligand variation, in the order PPh3 &#60; PMe3, in proceeding from (2) to (1), whereas data for the vinylidene/alkynyl complexes (3) and (4) are experimentally indistinguishable. The quadratic non-linear optical data for (1) and (2) are comparable to those of their 4-nitrophenylalkynyl analogues, however, (1) and (2) are more optically transparent.
