OSTI ID:1004882
Neodymium (III) chloride reacts with sodium isopropoxide in isopropyl alcohol to produce a complex which has been characterized by an x-ray crystal structure determination to be hexa-isopropoxy-nona({mu}{sub 2}-isopropoxy)-di-({mu}{sub 3}-isopropoxY)-({mu}{sub 6}-chloro-hexa-neodymium), Nd{sub 6}[OCH(CH{sub 3}){sub 2}]{sub 17}Cl. The pale blue crystals are monoclinic, space group P2{sub 1}/n with cell dimensions a = 24.52(2) {angstrom}, b = 22.60(2) {angstrom}, c = 14.22(1) {angstrom}, and {beta} = 101.05(5){sup o}; for four molecules in the unit cell the calculated density is 1.636 gm/cc. The structure was refined by full-matrix least-squares to a conventional R factor of 0.076 for 2327 data with I > 2{sigma}. The six neodymium atoms form a trigonal prism centered about the chloride atom. Six isopropoxide groups are terminal, nine are edge bridging, and two are bridging a trigonal face of the prism yielding six two-coordinate, nine three-coordinate, and two four-coordinate oxygen atoms, respectively. The average Nd-Cl distance is 3.05(1) {angstrom}. The average Nd-O distances for oxygen atoms which are bonded to one, two, and three Nd atoms are 2.05(2) {angstrom}, 2.36(4) {angstrom}, and 2.45(5) {angstrom}, respectively.
