Bis[6-methoxy-2-[(4-methylphenyl)iminiomethyl]phenolate-κO1]tris(nitrato-κ2O,O′)ytterbium(III) monohydrate

Abstract

The crystal structure of title compound, [Yb(NO3)3(C15H15NO2)2]·H2O, contains two Schiff base 2-[(4-methylphenyl)iminomethyl]-6-methoxyphenol (HL) ligands, three independent nitrate ions that chelate to the ytterbium(III) ion in an O,O′-bidentate manner and an uncoordinated water molecule. The coordination number of the YbIII ion is eight. The HL ligands chelate with a strong Yb—O(phenolate) bond and a weak Yb—O(methoxy) contact. The latter augments the coordination polyhedron to give a YbO10 bicapped square antiprism. Classical intermolecular O—H...O and N—H...O hydrogen bonds as well as weak C—H...O contacts contribute to the stability of the structure.
