Abstract/OtherAbstract:
We prepared single crystals of basic copper formate Cu(2) (OH)(3) HCO(2) (1) by hydrolysis of formate anions in an aqueous solution of copper formate. X-ray structure analysis showed that this material has a two-dimensional triangular lattice network with S=1/2. The temperature dependence of magnetic susceptibility revealed antiferromagnetic ordering at 5.4 K. A spin-flop transition was observed at about 20 kOe at 2 K, thereby indicating metamagnetic-like behavior. The saturation magnetization was almost one-half of the theoretical value at 2 K under 70 kOe. The magnetic behaviors of 1 were also discussed with regard to its crystal structure. The preparation method presented herein is convenient and available for single crystal growth of metal hydroxide derivatives with various anions.
