Bis[6-meth­oxy-2-[(4-methyl­phen­yl)iminiometh­yl]phenolate-κO (1)]tris­(nitrato-κ(2) O,O′)ytterbium(III) monohydrate

The crystal structure of title compound, [Yb(NO(3))(3)(C(15)H(15)NO(2))(2)]·H(2)O, 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 Yb(III) 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 YbO(10) 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.
