Tris-(1,2-N,N-dimethylaminomethylferrocenyl)stibine and its heterotrimetallic complex
摘要:
New tertiary chloro-bis(1,2-N, N-dimethylaminomethylferrocenyl)stibine (1) and tris-(1,2-N, N-dimethylaminomethylferrocenyl) stibine ligand (2) containing CH2NMe2 pendenant arm at the ortho-position have been synthesized. Stibine (2) reacts with PtCl42 and hetero trimetallic cis-PtCl2L (3) complex is obtained, where stibine (2) acts as a bidentate ligand. All these compounds were characterized by various physicochemical methods and their molecular structures were determined by X-ray diffraction analyses. It is to be noted that tris(1,2-aminomethylferrocenyl) stibine represents the first example of a structurally characterized ferrocenyl pnictogen where three 1,2-disubstituted ferrocenyl groups are attached to the central antimony atom and phosphorus analogue of the stibine is missing in the literature. Stibine (1) shows a hypervalent Sb-N interaction while stibine (2) does not show this interaction in solid state. (C) 2008 Elsevier B.V. All rights reserved.
