Synthesis and Structure of Heterobinuclear Complexes [AuCl(μ-Dien*)PtCl3] and [AuCl(μ-Dien*)PtCl3] · 0.5H2O

Abstract

New binuclear complexes [AuCl(μ-Dien*)PtCl₃] and [AuCl(μ-Dien*)PtCl₃] · 0.5H₂O, where Dien* is deprotonated diethylenetriamine, have been prepared and studied by elemental analysis, X-ray diffraction, and IR spectroscopy. The crystal structures are built of binuclear complexes of the composition [AuCl(μ-Dien*)PtCl₃] with the average Au⋯Pt intramolecular distance equal to 3.403 Å. Gold and platinum atoms have distorted square coordination; the (AuN₃Cl) and (PtNCl₃) coordination cores are found; the middle Dien nitrogen atom acts as a bridge bonding the Au and Pt coordination squares.
