The reaction of CuCl 2 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) Å, b=14.665(5) Å, c=7.883(3) Å, β=96.105(4)°, V=972.6(6) Å 3 , Z=2, D calc =1.645 Mg/m 3 , μ=1.691 mm -1 , F(OOO)=486, MoK α (λ=0.71073 Å), R1=0.0431 for [∣I∣≥2σ(I)] and R1=0.0680 for all 1944 unique reflections and 130 parameters. The structure exists as square planar Cu(H 2 O) 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 ${\rm N}{{\hskip -1pt -\!\!\!- \hskip-.5pt}}{\rm H}$ [ABSTRACT FROM AUTHOR]
