First hyperpolarizabilities of manganese(I)-chromium(0) sesquifulvalene complexes

The synthesis of monometallic manganese and bimetallic manganese- chromium complexes incorporating the sesquifulvalene derivatives 2-(2,4,6- cycloheptatrien-1-ylidene)indene (VI) and [(2,4,6-cycloheptatrien-1- ylidene)ethenylidene]cyclopentadiene (VII) is reported. Charge separation is observed upon complexation and stabilization of VI and VII by metal centers, and the spectroscopic and structural properties of [(VI)Mn(CO)3]BF4 (6), [(OC)3Mn(μ-VI)Cr(CO)3]BF4 (8), [(VII)Mn(CO)3]BF4 (13), and [(OC)3Mn(μ-VII)Mn(CO)3]BF4 (15) are clearly indicative of sesquifulvalene ligands coordinated in a dipolar η5 or μ-η5:η7 fashion, respectively. The coplanar cyclopentadienyl and cycloheptatrienyl fragments act as strongly coupled electrondonating and -accepting groups and strong negative solvatochromism is observed for complexes 6, 8, 13, and 15. Accordingly, exceptionally large first molecular hyperpolarizabilities β have been determined by means of hyper Raleigh scattering for the bimetallic species 8 and 15, as well as for some related compounds. The X-ray crystal structures of anti-[(OC)3Mn(μ-η5:η7-VI(CO)3] (8) and syn-[(OC)3Mn(μ-η5:η7- VII)Cr(CO)3] (15) are reported.
