摘要
A series of platinum(II) complexes have been prepared using cis-1,2-diaminocyclopentane and cis-3,4-diaminocyclopentanols; specifically; cis-[PtCl2(cis-1,2-diaminocyclopentane)] (A), cis-[PtCl2(cis,syn-3,4-diaminocyclopentanol)] (B), cis-[PtCl2(cis,anti-3,4-diaminocyclopentanol)] (C), and bis(cis,anti-3,4-diaminocyclopentanol)plantinum (II) tetrachloroplatinate (D). The complexes were synthesized from K2PtCl4 and the corresponding cis-diamines. Crystal structures of the Pt(II) complexes have been determined by X-ray single crystal diffraction. Parameters are as follows: space group P2(1)/n (no. 14), a = 7.8133(4), b = 13.5959(7), c = 9.8561(7) Angstrom, beta =113.201(4)degrees, V = 962.33(19) Angstrom(3), Z = 4 for A; space group P2(1)/n (no. 14), a =6.6076(2), b = 11.3481(4), c = 11.9739(4) Angstrom, beta = 98.364(2)degrees V = 888.30(9) Angstrom(3), Z = 4 for B; space group P2(1)/c (no. 14), a = 12.7358(2), b = 20.8072(5), c = 12.1253(3) Angstrom, beta = 112.6139(13)degrees, V= 2966.1(2) Angstrom(3), Z = 12 for C; space group P2(1)/c (no. 14), a = 10.0248(3), b = 8.9029(5), c = 11.1253(6) Angstrom, beta = 109.174(3)degrees, V = 937.85(15) Angstrom(3), Z = 2 for D. The coordination spheres about the Pt atoms are slightly distorted square planar geometries owing to the presence of the geometrically strained five-membered PtN2C2 ring.
