چکیده
The asymmetric unit of the title proton-transfer compound, C(5)H(16)N(2) (2+)·2C(7)H(4)NO(4) (-)·H(2)O, consists of two mono-deproton-ated pyridine-2,6-dicarb-oxy-lic acid mol-ecules as anions, viz. (py-2,6-dcH)(-), one diprotonated N(1),N(1)-dimethyl-propane-1,2-diamine mol-ecule as a cation, viz. (dmpdaH(2))(2+), and one water mol-ecule. The crystal packing shows extensive O-H⋯O, N-H⋯O, N-H⋯N and O-H⋯N and weak inter-molecular C-H⋯O hydrogen bonds. These inter-actions link the (dmpdaH(2))(2+) cation, the (py-2,6-dcH)(-) anions and water mol-ecule and play an important role in the stabilization of crystal packing.
