Abstract
The crystal and molecular structure oftrans-dichlorobis(oxazole)palladium-(II), Pd(C3H3ON)2Cl2, has been determined by single-crystal X-ray diffraction techniques using counter methods and has been refined by full-matrix least-squares procedures to a finalR index of 0.022. The complex crystallizes in the triclinic space groupP¯1 with unit cell dimensions ofa = 6.957(1),b = 7.506(1),c = 5.538(1) Å, α = 109.22(1), β = 91.37(1), and γ = 115.09(1) °, withZ = 1. The palladium(II) ion, located at an inversion center, is coordinated in a regular square-planar manner to two chloride ions at 2.293(1) Å and, at 2.016(2) Å, to the nitrogen atoms of two oxazole ligands. The planar oxazole rings are tilted 33 ° with respect to the PdN2Cl2 plane. Further verification of the presence of oxazole in the complex was obtained by high-resolution mass spectrometry. Crystals of Pd(C3H3ON)2Cl2 resulted irreproducibly from attempts to prepare single crystals of a previously reported dimeric palladium(II) disulfide complex by treating Pd(CH3CN)2Cl2 with a slight excess of diphenyl disulfide in benzene in the atmosphere. The source of the oxazole is not understood.
