SYNTHESIS, CHARACTERIZATION, AND CRYSTAL-STRUCTURE OF A COPPER(II) COMPLEX WITH QUINOLONE FAMILY MEMBER (CIPROFLOXACIN) - BIS(1-CYCLOPROPYL-6-FLURO-1,4-DIHYDRO-4-OXO-7-PIPERAZIN-1-YLQUINOLINE-3-CARBOXYLATE) COPPER(II) CHLORIDE HEXAHYDRATE

The synthesis of the coordination compound [Cu(CF)(2)]Cl-2.6H(2)O is reported. Its crystal structure is presented and discussed. The title compound crystallizes in the triclinic space group P ($) over bar 1 with a = 9.369(2), b = 9.573(2), c = 11.206(2) Angstrom, alpha = 87.37(2), beta = 80.58(2), gamma = 86.25(2)degrees, V = 988.8 Angstrom(3), Z = 1, and D-c = 1.520 g cm(-3). A structure determination, using three-dimensional MoKalpha x-ray data, resulted in conventional R and Rw values of 0.0399 and 0.0988, respectively, for 3495 unique reflexions for which I > 2 sigma(I). Refinement was based on F-2. The copper atom at the center of inversion is surrounded in a plane by four oxygens (two of the carboxylate groups, two of the carbonyl groups), the corresponding Cu-O distances are 1.928(2) and 1.931(2) Angstrom. The two chlorine atoms are axially coordinated to Cu at larger distances than 2.688(2) Angstrom. The Cl atoms appeared to be disordered over three positions. The nearly planar moieties of Cu(CF)(2) are packed parallel in the unit cell interconnected via hydrogen bonds of the type N-H...O, O-H...Cl and O-H...O. The results of other physical measurements (TG, FT-IR, and various analyses) are also included.
