Monohydrido-bridged platinum(II)–gold(I) complexes. X-Ray crystal structure of [(Ph3P)2(C6Cl5)Pt(µ-H)Au(PPh3)]ClO4·2Et2O
Abstract
The compounds [(Ph3P)2RPt(µ-H)Au(PPh3)]ClO4(R = C6Cl5, C6H3Cl2-2,5, or C6H4Cl-p) have been obtained by reaction of the corresponding complex trans-[PtH(R)(PPh3)2] with [Au(thf)(PPh3)]ClO4 and they have been characterized by 1H and 31P n.m.r. spectroscopy. The molecular structure of [(Ph3P)2(C6Cl5)Pt(µ-H)Au(PPh3)]ClO4 has been determined by a single-crystal X-ray structural analysis. The crystals are triclinic, space group P1, with a= 22.866(7), b= 13.844(5), c= 11.392(4)Å, α= 110.79(3), β= 85.13(2), γ= 96.95(2)°, and Z= 2.
