Organometallic Group-13 Metal-Complexes of D-Block Elements .8. Reactions of Elemental Indium and Indium(I) Bromide with Nickel-Bromine Bonds - Structure of (Eta(5)-C5H5)(pH(3)P)Ni-Inbr2(O=pph(3))
The reactions of elemental indium and (InBr)-Br-I with the carbonyl-free organonickel complexes (eta(5)-C5H5)(PR(3))NiBr (R = CH3, C6H5) have been studied in some detail. Either redox reactions to yield the ionic products [(eta(5)-C5H5)(PR(3))(2)Ni][InBr4] (2a,b) occurred or the Ni-In bound systems (eta(5)-C5H5)(PPh(3))Ni-InBr3(OPPh(3)) (3a) and [(eta(5)-C5H5)(PPh(3))Ni]2InBr (4) were obtained in good yields. The new compounds were characterized by elemental analysis, NMR, and mass spectrometry. A short Ni-In bond of 244.65(9) pm was found for 3a. Single crystal data for (eta(5)-C5H5)(PPh(3))Ni-InBr2(OPPh(3)). THF (3a) : triclinic, P1 with a = 1124.9(3), b = 1353.2(4), c = 1476.4(4) pm, alpha = 94.74(2)degrees, beta = 101.78(2)degrees, gamma = 109.64(1)degrees, V = 2044(1) x 10(6) pm(3), Z = 2, R = 0.053 (R(w) = 0.063).
