Bis{6-meth-oxy-2-[(4-methyl-phen-yl)iminiometh-yl]phenolate-κO,O'}tris-(nitrato-κO,O')holmium(III) mono-hydrate.

ABSTRACT: The crystal structure of the title compound, [Ho(NO(3))(3)(C(15)H(15)NO(2))(2)]·H(2)O, contains two Schiff base 6-meth-oxy-2-[(4-methyl-phen-yl)iminiometh-yl]phenolate (L) ligands, three independent nitrate ions that chelate to the Ho(III) ion with O atoms and a hydrate water mol-ecule. The coordination environment of the Ho(III) ion is ten-coordinate. The L ligands chelate with a strong Ho-O(phenolate) bond and weaker Ho-O(meth-oxy) contacts. The latter can be inter-preted as the apices of the bicapped square-anti-prismatic [HoO(10)] polyhedron. Inter-molecular N-H⋯O hydrogen bonds occur. Intra-molecular O-H⋯O inter-actions link the complex mol-ecules and uncoordinated water mol-ecules.
