A new hexanuclear copper(Ⅱ) complex,[Cu6(DPPZ)4(btc)4(H20)s]·5H20 (1,DPPZ= dipyrido[3,2-a:2,3-e]phenazine,H3bte = 1,3,5-benzenetricarboxylic acid),has been hydrothermally synthesized and structurally characterized by X-ray single-crystal diffraction,elemental analyses,IR,and thermogravimetric analysis. Its crystal structure is of triclinic system,space group P(1) with a = 12.489(4),b = 14.234(5),c = 14.484(5) (A°),α= 82.848(4),β= 79.399(4),γ = 73.646(4)°,V = 2421.2(13) (A°)3,Z = 1,Cu6C108H78N16O37,Mr = 2573.17,Dc = 1.752 g/cm3,μ = 1.398 mm-1,F(000) = 1308,GOOF = 1.011,the final R = 0.0495 and wR - 0.1030 for 5420 observed reflections with Ⅰ > 20(I). In 1,four btc3- ligands act as bridges between six neighboring Cu atoms to form an unusual hexanuclear copper cluster. The clusters are further connected by two types-of OH…O and O-H…N hydrogen bonds,generating a three-dimensional supramolecular structure. In addition,intermolecular and intramolecular π-π stacking interactions further consolidate the three-dimensional supramolecular framework of 1.
