Crystal Structures of trans-Diiodidobis(2-hydroxyethylamine) platinum(II) and trans-Dichloridobis(2,2 '-dihydroxydiethylamine) platinum(II)

摘要

The crystal structures of trans-diiodidobis(2-hydroxyethylamine)platinum(II), trans-[PtI2(mea)(2)], (1) and trans-dichloridobis(2,2'-dihydroxydiethylamine)platinum(II), trans-[PtCl2(dea)(2)], (2) were determined by single crystal X-ray diffraction experiments. Crystallization of (1) occurs in the monoclinic space group P2(1)/c with a = 9.457(1) angstrom, b = 14.719(2) angstrom, c 8.246(1) angstrom, Z = 4 for d(calc) = 3.235 mg/m(3) while crystallization of (2) occurs in the tetragonal space group P4(2)/mbc, a = 9.8624(6) angstrom, c = 14.2998(9) angstrom, Z = 4 for d(calc) = 2.274 mg/m(3). The square-planar coordination geometry of both complexes is formed by two N atoms of the 2-hydroxyethylamine (1) or 2,2 '-dihydroxydiethylamine (2) ligands in trans positions and two I- (1) or Cl- (2) anions. Both structures are stabilized by intra- and intermolecular hydrogen bonds.
