Je. Bender et al., X-ray crystallographic and theoretical comparison of Ge[2,4,6-(CF3)(3)C6H2](2) and Ge[N(SiMe3)(2)](2) as ligands in (Ph3P)(2)NiGeX2 complexes, ORGANOMETAL, 18(8), 1999, pp. 1547-1552
A new transition metal germylene complex, (Ph3P)(2)NiGe[2,4,6-(CF3)(3)C6H2]
(2) (2), has been synthesized and structurally characterized. The metrical
parameters of complex 2 are compared and contrasted with the previously syn
thesized complexes (Ph3P)(2)NiGe[N(SiMe3)(2)](2) (3) and (Et3P)(2)PtGe[N(Si
Me3)(2)](2) (1). Nonlocal BP86 density functional calculations support the
presence of Ni-Ge d-p pi bonding in complexes 2 and 3.
