      The synthesis and physico-chemical characterization of a novel organic-inorganic hybrid material,1-(2,5-dimethylphenyl)piperazine-1,4-dium tetrachloridocuprate(II), have been reported. This compoundcrystallizes in the monoclinic system with the space group of P21/n and cell parameters a = 9.833(3),b = 16.337(2), c = 10.452(3) Å,β = 102.13(4)

      ◦, Z = 4 and V = 1641.5(7)Å3. In the title salt,$(C_{12}H_{20}N_{2})$ $[CuCl^{4}]$, the geometry of the $CuCl^{ 2−}$4 ion is intermediate between tetrahedral and square planar. Inthe atomic arrangement tetrachlorocuprate anions and the piperazine-1,4-dium cations are held together via NH.

      . .Cl and C-H. . .Cl to give a 1-D hybrid chain running along the a-axis. The six-membered piperazinediumring adopts a chair conformation. The vibrational absorption bands were identified by infrared spectroscopy.Magnetic measurements reveal that moderate antiferromagnetic (AF) Cu–Cu interactions dominate in thetitle compound.
