THE YTTRIUM CHLORIDE-1,10-PHENANTHROLINE INTERACTION - SYNTHESIS AND X-RAY CRYSTAL-STRUCTURE OF THE COMPLEX [Y(OH)(H2O)2(PHEN)2]2CL4.2(PHEN).MEOH

Investigations on the reaction between YCl3.H2O and phen (1,10-phenanthroline) led to the isolation of the title compound. The synthesis, IR and X-ray structural characterization are described. The crystal contains centrosymmetric binuclear dications [Y2(phen)4(mu-OH)2(H2O)4]4+, uncoordinated chloride anions, two clathrated phen molecules and a disordered methanol molecule. The yttrium ions are eight-coordinated with square antiprismatic geometry to the nitrogen atoms of two phen molecules, to bridging hydroxyl groups and to two water molecules. The Y...Y1 separation in the dimer is 3.651(2) angstrom.
