Keywords： lanthanum complex

A new complex of lanthanum orotate [La(C5H3N2O4)2(OH)(H2O)6]·2(C5H4N2O4)·9H2O was synthesized using a hydrothermal method.The crystal structure was determined with help of single crystal X-ray diffraction analysis.The complex crystallized in orthorhombic system, Cmc2(1) space group.In the complex, the center lanthanum(Ⅲ) ion was nine-coordinated with coordination geometry of a distorted monocapped square antiprism, in which two of the nine coordinated oxygen atoms were from two orotate ligands in a monodentate mode, one oxygen atom from a hydroxyl, and the others from six coordinated water molecules.The mononuclear complex [La(C5H3N2O4)2(OH)(H2O)6]·2(C5H4N2O4)·9H2O was linked through the hydrogen bonds into an infinite supermolecular honeycomb structure.
