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.
