A new Cadmium!-Ciprofloxacin ionic compound, (HCPFX)2CdCl4·3H2O, is synthesized and its crys- tal structure is determined. The crystallography data are as follows, monoclinic, space group P21/c, a=1.01039(6) nm, b=1.39989(9) nm, c=2.82245(18) nm, β=95.765 0(10)°, V=3.972 0(4) nm3, Z=4, Dc=1.627 g·cm-3, F(000)= 1984. R1=0.0540, wR2=0.1503 (I>2σ(I)). In the title compound, four chloride ions are coordinated to the cadmi- um ion forming a slightly distorted tetrahedron. Both Ciprofloxacin and the compound were assayed against gram- positive and gram-negative bacteria by doubling dilutions method, the compound shows the same minimal in- hibitory concentration (MIC) as the Ciprofloxacin against S. Aureus, M. Lutens, E. Coli and P. Aeruginosa bacte- ria. The inhibitory effect of the two compounds on leukemia HL-60 cell line has been measured by using MTT (Methyl-Thiazol-Tetrozolium) assay method. The results indicate that the complex has very strong inhibitory effect on HL-60 cell line. CCDC: 259367.
Two novel coordination polymers, [Cu(nip)(phen)]n (1) and [Co2(nip)2(phen)2]n (2), have been synthesized by hydrothermal synthesis using 5-nitroisophthalic acid (H2nip), 1,10-phenanthroline (phen) and metal salts and structurally characterized by X-ray single-crystal structure analysis. The results indicated that the nip ligand in compound 1 has a μ3 mono-atomic bridging-monodentate coordination mode and the structure is a two-dimensional network, while the nip ligand in compound 2 has a chelating-bridging coordination mode and the structure is a one-dimensional network.

The title complex, [Cu(Hsal)2(py)2], was synthesized by layered solution technique and structurally characterized by single crystal X ray. The copper atom has a square pyramidal geometry and the coordination number is five. The molecular structure is linear one dimensional network. There is a stacking effect between pyridine ligands of neighbouring 1 D chains and the molecular structure is extended into two dimensional stacking network. Two salicylates in the complex have a position of crab pincers like, in which one salicylate is unidentate and another coordinates through the carboxylate group and phenyl group unidentately.
