The complex crystallizes in the monoclinic system, space group C2/c with a = 14.997(3), b = 18.108(4), c = 17.237(3) A, β = 96.61(3)°, V = 4649.9(16) A3, Z = 4, C48H38N4O12P4Zn3, Mr = 1182.87, Dc = 1.690 g/cm3^,μ = 1.743 mm^-1, F(000) = 2400, the final R = 0.0363 and wR = 0.0963. In the structure, the connectivity between two 5-coordinated Zn(II) atoms and four phosphonates as well as two Phen ligands form a Zn2(PhPO3H)2(PhPO3)2(Phen)2 unit, and such a neighboring unit is bridged by 4-coordinated Zn(II) to give rise to a 1D chain along the c axis. The π-π stacking interactions between Phen rings assemble adjacent chains packed together to form a 3D supermolecular architecture.展开更多

The results showed that HL as a bidentate ligand coordinated with transition metal ions to form four-coordination complexes. The antibacterial activity was studied by using the filter scraps diffusion method, and the results indicated that the ligand and the complexes had a low bacteriostatic activity against S. Aureu, P. Aeruginosa and E. Coli. The low in vitro antitumor activity of the title complexes was also observed by using MTT method against KB, A2780, Bel7402 and HELF.展开更多
