Synthesis and crystal structure of a dinuclear praseodymium nitrate complex

Dinuclear supramolecular complex of praseodymium nitrate with an unsymmetrical tipodal ligand benzyl-N,N-bis[(2′-benzylaminoformyl)phenoxyl)ethyl]-amine (L), have been prepared. The X-ray single-crystal diffraction analysis indicates that this complex was crystallized in the monoclinic system, space group P21/c with parameters a = 16.736(3), b = 14.042(3), c = 19.782(4) A, β = 101.823°, V = 4550.50(16) A3, Z = 4. The structure was refined to the final R1 = 0.0473. The complex units are linked by the intermolecular hydrogen bonds to form a three-dimensional (3D) netlike supramolecuar structure.
