Structural and spectroscopic characterisation of the mixed valence platinum complex PtdabI3 (dab=o-diaminobenzene)
摘要:
The new mixed valence platinum complex PtdabI(3) (dab = o-diaminobenzene) (1) has been prepared and characterised. The crystal structure consists of separate units of planar Pt(II)dabI(2) and octahedral Pt(IV)dabI(4) molecules. The latter are arranged in linear chains with rather short intermolecular I ... I-contacts (3.478 Angstrom) which are responsible for charge transfer interactions. In the resonance Raman spectrum strong intensity enhancements and extended overtone progressions of the symmetric I-Pt-I stretching mode have been observed. (C) 1999 Elsevier Science S.A.
