A new lanthanum(III) complex containing acetyl-acetone and 1H-imidazole.

ABSTRACT: In the title complex, di-aqua-(1H-imidazole-κN³)(nitrato-κ²O,O')bis-(4-oxo-pent-2-en-2-olato-κ²O,O')lanthanum(III), [La(C₅H₇O₂)₂(NO₃)(C₃H₄N₂)(H₂O)₂], the La atom is coordinated by eight O atoms of two acetyl-acetonate (acac) anions acting as bidentate ligands, two water mol-ecule as monodentate ligands, one nitrate anions as a bidentate ligand and one N atom of an imidazolate (ImH) molecule as a monodentate ligand. Thus, the coordination number of the La atom is nine in a monocapped square anti-prismatic polyhedron. There are three types of inter-molecular hydrogen bonds between ligands, the first involving
