Beiträge zur chemie organometallischer metallacyclischer nebengruppenmetallverbindungen: IX. Eine ungewöhnliche koordinationsgeometrie des platin(II) in dem homoleptischen metallacyclopentankomplex [Li(PMDETA)] 2P [formula omitted]H 2) 2

Abstract

Reaction of [Li 2(Et 2O)]P t(CH 2CH 2CH 2C H 2) 2 ( 1) with N, N, N′, N″, N″-pentamethyldiethylenetriamine (PMDETA) in diethylether (Et 2O) gives [Li(PMDETA)] 2P t(CH 2CH 2CH 2C H 2) 2 ( 2). The complex has been characterized by DTA analysis, 1H and 13C NMR spectroscopy and X-ray crystallography. The thermal properties and the structures of 2 and [Li(TMEDA)] 2P t(CH 2CH 2CH 2C H 2) 2 ( 3) indicate the significant difference of the influence of PMDETA and N, N, N′, N′-tetramethylethylenediamine (TMEDA) on the platinacyclopentane system.
