摘 要：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.
