Cu(Ⅱ) complex%crystal structure%tripodal ligand
A pyridine-copper inclusion complex with [Cu(py)4Cl]+ core was prepared in the presence of tripodal ligand tbst {tbst = 1,3,5-tris(2-benzimidazol)sulfanylmethyl-2,4,6-trimethyl- benzene}, and its structure has been determined. It crystallizes in triclinic, space group Pī with a = 9.0822(2), b = 17.6026(4), c = 18.7156(4)(A°),α= 93.40,β= 91.2980(1),γ= 91.5560(1)°, V = 2984.81(1)(A°)3, C58H63Cl2CuN11O4S3, Mr = 1208.81, Z = 2, F(000) = 1262, Dc = 1.345 g/cm3,β= 0.615 mm-1, R = 0.0713 and wR = 0.1307 for 7798 observed reflections (I > 2σ(1)). X-ray analysis reveals that the uncoordinated tbst and pyridine as guest molecules are included in the complex with formula {[Cu(py)4Cl]Cl}@(tbst)@(py)@4H2O. The tbst, pyridine, aqua and Cl- anion in the com- plex form extensive hydrogen-bonding interactions, building up a quasi-dinuclear structure.
