Synthesis and nonlinear optical properties of carbonylrhenium bromide complexes with conjugated pyridines

Carbonylrhenium bromide complexes with conjugated pyridines fac-Br(OC)3ReL2 (L = FcCH:CH-p-C5H4N (Fc = ferrocenyl), FcCH:CHC(Me):CHCH:CHCH:C(Me)CH:CH-p-C5H4N, 1,1'Fc(CH:CH-p-C5H4N)2 p-Me2NC6H4CH:CHCH:CH-p-C5H4N (I), and p-Me2NC6H4CH:CHC(Me):CHCH:CHCH:C(Me)CH:CH-p-C5H4N) and cis-Br(OC)4ReL (L = FcCH:CH-p-C5H4N (II) and p-Me2NC6H4CH:CHCH:CH-p-C5H4N) were synthesized. The structures of I (monoclinic, C2/c, a = 18.3826(1), b = 15.1048(1), c = 28.5866(1) .ANG., b = 92.848(1) Deg, V = 7927.71(7) .ANG.3, Z = 8, rc = 1.636 g/cm3, m(MoKa) = 4.317 mm-1, F(000) = 3848, 7804 independent reflections, 480 refined parameters, R1 = 0.0726, wR2 = 0.1723) and II (rhombohedral, R.hivin.3, a = 30.357(4), c = 12.398(2) .ANG., V = 9895(2) .ANG.3, Z = 18, rc = 2.016 g/cm3, m(MoKa) = 8.003 mm-1, F(000) = 5688, 2930 independent reflections, 262 refined parameters, R1 = 0.0578, wR2 = 0.1048) were detd. by x-ray diffraction anal. Compd. I exhibits a remarkable quadratic hyperpolarizability. [on SciFinder (R)]
