Abstract

The reactions of N,N-dimethylaminopropyl chalcogenolates with platinum(II) compounds have been carried out and complexes of the types [PtCl(ECH2CH2CH2NMe2)]2 (1) (E = S (1a) and Se (1b)), [Pt(ECH2CH2CH2NMe2)2]n (2) (E = S (2a) and Se (2b)), [(PtCl2)2{(Me2NCH2CH2CH2E)2}]n (3), [PtX(SeCH2CH2CH2NMe2)]2 (4) (X = SePh (4a) and OAc (4b)) and [PtCl(ECH2CH2CH2NMe2)(PR3)]n (5) (E = S, Se, Te) have been isolated. These complexes have been characterized by elemental analysis, IR, UV–Vis, NMR (1H, 13C, 31P, 77Se, 195Pt) spectroscopy and FAB mass spectral data. The structures of [PtCl(SeCH2CH2CH2NMe2)]2 (1b) and [PtCl(SCH2CH2CH2NMe2)(PPr3)]2 (5a) have been established by single crystal X-ray diffraction data. Both the molecules have dimeric structures. In 1b, two platinum atoms are held together by symmetrically bridging Se atoms of the chelating selenolate groups. In 5a, two thiolates form a four-membered Pt2S2 bridge with dangling NMe2 groups.
