【 摘 要 】

The first benzohydrazide complex of a lanthanide is reported. In the title compound, [Sm(C8H4O4)(C7H8N2O)3(H2O)2]NO3, systematic name di­aqua­tris­(benzohydrazide-κ2N,O)(isophthalato-κO)samarium(III) nitrate, the SmIII ion is nine-coordinated in a distorted tricapped trigonal–prismatic geometry by three oxygen atoms and three nitro­gen atoms from three benzhydrazide (bzz) ligands, one oxygen atom from the isophthalate (itp2−) ligand, and two oxygen atoms from coordinated water mol­ecules. The nitrate group is disordered over two sets of sites with occupancy factors of 0.310 (17) and 0.690 (17). In the crystal, adjacent mol­ecules are linked into chains via pairs of O—H⋯O and N—H⋯O hydrogen bonds between the carboxyl­ate acceptor and the coordinated water and amine NH2 donors. Mol­ecules are further stacked by π–π inter­actions involving the benzene ring of the itp2− ligands, forming double chains that extend in the b-axis direction. These double chains are further linked into a three-dimensional supra­molecular network via hydrogen bonds (O—H⋯O, N—H⋯O and C—H⋯O) between the complex mol­ecule and the nitrate groups along with C—H⋯π and π–π inter­actions involving the benzene rings of the bzz and itp2− ligands.
