Mr=1196.89, orthorhombic, P212121,a=15.592(4), b=17.419(6), c= 17.982(5)A, V=4883.8A3, Z=4. The structure was solved by direct methods and Fourier synthesis and refined by block-diagonal and full matrix Least-squares method to a .final R of 0.027 for 3916 independent observable reflections I>3 (I). The ten donor oxygen atoms are coordinated to centre metal ion Th(IV) forming a irregular coordination polyhedron. The three nitrate groups and the OBM anion are all bidentate ligands and the average bond lengths of Th-O(NO3) and Th-O(DBM) are 2.60A and 2.37A, respectively. The average coordination bond length of Th-O(TPPO) is 2.37A. Mr = 1196.89, orthorhombic, P212121, a = 15.592 (4), b = 17.419 (6), c = 17.982 (5) A, V = 4883.8A3, Z = 4.
