  A dinickel complex with bridging silyl ligands, [Ni(PCy3)}(2)(mu-SiHPh2)(2)] (1), prepared from [Ni(cod)(2)], PCy3, and H2SiPh2, underwent exchange of the PCy3 ligands with 1,2-bis(dimethylphosphino)-ethane (dmpe) to yield a complex coordinated by the two bidentate ligands, [Ni(dmpe)}(2)(mu-SiHPh2)(2)]. Reactions of diarylacetylenes, ArC CAr (Ar = C6H5, C6H4OMe-4, C6H4Me-(4), C6H4F-(4), C6H4CF3-4, C6H4CN-4), with 1 in a 4/1 ratio afforded 1,2-bis(E)-1,2-diarylethenyl}-1,1,2,2-tetraphenyldisilanes via addition of the Si-H bond of the bridging silyl ligand to the alkynes and subsequent coupling of the resulted tertiary silyl ligand. X-ray crystallography of the dialkenyldisilanes resulted in three kinds of conformation of the C=C-Si-Si-C=C chain depending on the aryl group at the vinyl carbon. The disilane with phenyl substituents, 4a (Ar = C6H5), contained a planar C=C-Si-Si-C=C alignment with small Si-Si-C=C torsion angles (1.7(5) and 6.9(5)degrees). The other dialkenyldisilanes, 4b,c,e,f, had much larger torsion angles (30.9(3)-49.2(3)degrees), and the twisted conformation of the molecules was classified into two types. Compound 4a exhibited a fluorescence maximum at 488 nm in the solid state, while 4b f showed peaks at 393-427 nm. The red shift in the emission of 4a is ascribed to orthogonal intramolecular charge transfer (OICT) from the electron-donating Si Si to accepting C=C bonds.
