Abstract: | Synthesis and single crystal X-ray diffraction study were carried for compound {Cu(C11H16N4)2(N3)](ClO4)} · H2O (I). The structure is molecular, and the Cu2+ ion is in a five-coordinated compressed trigonal bipyramid environment. Copper ion is bound to five N atoms, in which four
N atoms are from two chlelating ligands 2-(piperidin-1-ylmethyl)pyridine and the fifth N donor is from a monodentate azido
ligand. The complex cations Cu(C11H16N4)2(N3)]+, the perchlorate anions, and solvent water molecules are further joined into three dimensional supramolecular networks by
rich hydrogen bonds including strong O-H…N between solvent water and azide ion and O-H…O between solvent water and perchlorate
ion, and weak hydrogen bonds C-H…O, and weak bifurcated hydrogen bonds C-H/C-H…N in which N atom of azide ion serving as bifurcated
acceptor and two C-H groups as donors. |
