摘要：

The reaction of CuCl2 with 2-amino-5-cyanopyridine and HCl in 1-propanol gave bis(2-amino-5-cyanopyridinium) diaquadichlorocopper(II) dichloride (1). Crystal data for 1 are: monoclinic, space group: P2(1)/c, a=8.461(3) Angstrom, b=14.665(5) Angstrom, c=7.883(3) Angstrom, beta=96.105(4)degrees, V= 972.6(6) Angstrom(3), Z=2, D-calc=1.645 Mg/m(3), mu=1.691 mm(-1), F(OOO)=486, MoKalpha(lambda=0.71073 Angstrom), R1=0.0431 for [\I\ greater than or equal to 2sigma(I)] and R1=0.0680 for all 1944 unique reflections and 130 parameters. The structure exists as square planar Cu(H2O)(2)Cl-2 units with long semi-coordinate bonds to the cyano nitrogens of the 2-amino-5-cyanopyridinium ions. Hydrogen bonding from the water molecules and N-H hydrogens to the chloride ions stabilizes the lattice.
