摘要：

The preparation and structural characterization of a new complex (C11H18N2O)(2)[CoCl4](2).H2O (I) are described. The crystal structure determination shows that the title compound crystallizes in the Pccn space group of the orthorhombic system. The unit cell dimensions are as follows: a = 29.090 , b = 9.774 , and c = 11.751 , with Z = 4. The crystal structure of this salt was solved by Patterson methods and refined by full-matrix least squares on F (2) to final values of R = 0.0333 and wR = 0.0771. The tetrahedral (CoCl4)(2-) anions are connected to the 1-(2-methoxyphenyl)piperazinium cations by hydrogen bonding (N-H a <-Cl and O-H a <-Cl). The crystals were characterized by employing several techniques such as single-crystal X-ray diffraction, thermo differential and gravimetric analyses, IR, RMN and UV-vis spectra, and fluorescence properties. Moreover, magnetic susceptibility measurements indicate that the compound exhibits weak antiferromagnetic coupling interaction.
