Abstract
The title compound chlorotris(PTA)platinum(II) chloride hydrate methanolate (PTA=1,3,5-triaza-7-phosphaadamantane), [C19H42Cl2N9O2P3Pt] is monoclinic, witha=10.832(1),b=21.306(7),c=12.702(3)A,β=100.42(5)°,V=2883(2)A3,Z=4,Dx=1.814 g cm−3,μ=53.0 cm−1,F(000)=1568,T=298K in space groupP21/c. The structure was solved by heavy atom and Fourier methods and refined toR=0.051 for 4319 unique observed reflections. The complex exhibits approximately square-planar geometry about the Pt atom and a significant trans effect, with bond lengths Pt-Cl1=2.3371(2), Pt-C12 (ionic)=4.463(4), Pt-Ptrans(to cl)=2.233(2), Pt-Pcis,ave=2.323(3)A and bond angles Cl-Pt-Pcisave 83.60(3), Ptrans-Pt-Pcis,ave 96.49(6)°. The H2O is apparently hydrogen bonded to two N atoms on different cations, and the methanol OH group to the chloride anion.
