Abstract: | 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. |
