Abstract: | Synthesis and structure of a novel thermochromic complex (CH8N4)2CuCl6] are reported. X-ray analysis of the compound was carried out for a single crystal 0.4×0.2×0.05 mm in size (a bright-yellow plate). The monoclinic unit cell parameters are a=7.167(1), b=15.561(3), c=7.328(1) Å, β=118.73(3)°, V=716.7(2) Å3, space group P21, Z=2 (CH8N4)2CuCl6] dcalc=1.99 g/cm3, μ(MoKα)=2.65 mm?1, R=0.0264, and Rw=0.0290 for 1411 Ihkl>2σI. |
