Crystal structures of trans-diiodidobis(2-hydroxyethylamine) platinum(II) and trans-dichloridobis(2,2’-dihydroxydiethylamine) platinum(II)

Abstract

© ISUCT Publishing. The crystal structures of trans-diiodidobis(2-hydroxyethylamine)platinum(II), trans-[PtI2 (mea)2 ], (1) and transdichloridobis(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 P21 /c with a = 9.457(1) Å, b = 14.719(2) Å, c = 8.246(1) Å, Z = 4 for dcalc = 3.235 mg/m3 while crystallization of (2) occurs in the tetragonal space group P42 /mbc, a = 9.8624(6) Å, c = 14.2998(9) Å, Z = 4 for dcalc = 2.274 mg/m3. 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.
