Crystal Structure of the Lanthanum Nitrate Complex with N-(2-Amino-4-methylpyridinyl)benzoylacetamide

Abstract

A solid complex of lanthanum nitrate with a β-diketonate-type ligand, N-(2-amino-4-methylpyridinyl)benzoylacetamide, was synthesized. The title complex was crystallized in the monoclinic system, space group C2/c with a = 25.005(5)Å, b = 11.636(2)Å, c = 17.706(3)Å, β = 124.837(1)°, V = 4228.35(1)ų, Z = 4. The complex has a symmetry of C₂, and the geometry of La(III) is a distorted bicapped square antiprism. In the structure of the title complex, a 3D supramolecular network is formed by hydrogen-bond interactions.
