资源简介：
The tetrachlorocuprate(II) ion can crystallize in two different structures with the piperazinium dication (pipzH2).
Both structures contain discrete CuCl42- species. A yellow compound (pipzH2)[CuCl4]·2H2O (1) is monoclinic
(C2/c, Z = 4, a = 10.538(3) Å, b = 7.4312(5) Å, c = 17.281(4) Å, β = 111.900(10)°) and contains the CuCl42-
ion as a distorted tetrahedron. A green compound (pipzH2)2[CuCl4]·Cl2·3H2O (2) is triclinic (P1̄, Z = 2, a =
9.264(3) Å, b = 10.447(2) Å, c = 11.366(2) Å, α = 68.38°, β = 82.86(2)°, γ = 83.05(2)°) and contains the
CuCl42- ion with a square planar geometry. This latter compound shows thermo/photochromism, changing from
green to yellow upon heating or laser irradiation.
