Abstract
A novel neodymium(III) chloride complex with 2,4'-bipyridine (bpy), (bpyH)[Nd(H2O)9]Cl4·bpy·H2O, has been synthesized, crystallized and characterized by single-crystal X-ray diffraction and thermal analysis. The crystal is nine-coordinate homoleptic mononuclear aqua-complex and crystallizes in the triclinic P-1 space group with two formula units in the unit cell related by a pseudo-translation of b/2. In the crystal structure, each [Nd(H2O)9]3+ ion is hydrogen-bonded in the same way to one 2,4'-bipyridine molecule, one 2,4-bipyridinium cation, and chloride anions. Lattice water molecules form hydrogen-bonds which further stabilize the framework. The thermal properties of compound in the solid state were studied using TG-DTG techniques under dynamic flowing air atmosphere.
