The addition-reaction product of 1,1,1,4,4,4-hexachloro-1, 4-disilabutane with N-methylimidazole
The product of the addition reaction of 1,1,1,4,4,4-hexachloro-1, 4-disilabutane with N-methylimidazole is &mgr;-ethylene-C(1):C(2)-bis[dichlorotris(1-methylimidazole-N(3))sili con(IV)] dichloride, C(26)H(40)Cl(4)N(12)Si(2)(2+).2Cl(-). Two of the six Cl atoms are replaced by aromatic nitrogen bases and the coordination sphere of silicon is extended from four to six. The molecule is located on a crystallographic centre of inversion. The environment around the Si atom can be described as a slightly distorted octahedron with the Cl atoms occupying axial positions and the three N-methylimidazole ligands and the ethylene bridge in the equatorial plane.
