Abstract

The single crystal X-ray structure of the compound [(Me₃P-Au- Selenourea)₂²⁺ 2Cl^-] has been determined. The [Me₃P-Au-(selenourea)] units are dimerized and adopt a binuclear structure characterized by a metal-metal interaction (Au-Au:3.0386(5) Å) and a torsion angle of 69.71(2)°. Hydrogen bonding takes place between the selenourea ligands and the chloride ions. The principal components of the ⁷⁷Se, ³¹P and ¹³C shielding tensors were determined from solid-state NMR data.
