چکیده
In the title compound, C(3)H(5)N(2) (+)·C(2)HO(4) (-), the anions form centrosymmetric dimers through cyclic O-H⋯O hydrogen-bonding associations [graph set R(2) (2)(10)]. These dimers are then linked through a cyclic R(4) (2)(10) N-H⋯O hydrogen-bonding association involving two cations and the carboxyl O-atom acceptors of separate anions, giving chain structures extending across the (111) plane.

The title solvated salt, C21H17N7 (2+)·SO4 (2-)·CH3OH, was obtained when we attempted to prepare the complex of ferrous sulfate and 2,6-bis-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]pyridine in methanol. The dihedral angles between adjacent pyridine and pyrazole rings range from 3.8 (1) to 13.4 (1)°. An intra-molecular N-H⋯N hydrogen bond occurs. In the crystal, N-H⋯O and O-H⋯N hydrogen bonds between s...

In the title salt, C2H5N4 (+)·C2HO4 (-), the hydrogen oxalate anions form corrugated chains parallel to the c axis, linked by inter-molecular O-H⋯O hydrogen bonds. The 5-amino-1H-1,2,4-triazol-4-ium cations are connected into centrosymmetric clusters via weak C-H⋯N hydrogen bonds forming nine-membered rings with an R 3 (3)(9) motif. These clusters are inter-connected via anions through N-H⋯O hy...
