Abstract

A new phosphine stabilised Au-Pd cluster compound [(dmpi)2Pd(AuPPh3)6](NO3) 2 (1) was prepared by direct reaction of dmpi = 2,6 dimethyl phenyl isonitrile with the cluster [(PPh3)Pd(AuPPh3)6](NO3) 2 (2) under a nitrogen atmosphere. The structure of this cluster is in agreement with 31P{1H} NMR and FABMS data. Two isonitrile groups substitute the PPh3 group in the cluster 2. Infrared data confirm (NO3) as the counterion. Single crystal X-ray diffraction results show that 1 has a spheroidal structure in which the PdAu6 framework has a Pd centred atom. Compound 1 crystallises as a diethyl ether solvate with the following crystal data: monoclinic space group P21/c, a = 25.2737(2), b = 19.1781(3), c = 25.4434(4) Å, β = 103.065 (1)°, V = 12013.2(3) Å3, Z = 4, residuals R = 0.0679 and Rw = 0.0769 for 8192 observed reflexions and 300 variables, Mo Kα radiation, -100°C.
