In the title hydrated salt, C(16)H(13)ClN(3) (+)·Cl(-)·2H(2)O, a small twist is evident in the cation so that the chloro-benzene ring is not coplanar with the central hydrazinyl group [the N-C-C-C torsion angle = -4.8 (12)°]. The conformation about the imine N=C bond [1.284 (10) Å] is E. The components of the structure are connected into a three-dimensional architecture via O-H⋯O, O-H⋯Cl and N-...

In the title complex, [Cu(C(7)H(4)NO(4))(C(11)H(10)N(3)O(2))]·2H(2)O, the Cu(II) atom is in a distorted octa-hedral geometry. The equatorial plane is formed by two N atoms and one O atom from 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate and by one N atom from pyridine-2,6-dicarboxyl-ate (pdc). Two pdc O atoms occupy the axial positions. Water mol-ecules are hydrogen bonded to the complex mol-ecul...

In the title compound, C(6)H(10)N(3) (+)·C(7)H(3)N(2)O(6) (-)·2H(2)O, the amino-pyrimidine mol-ecule is protonated at one of the pyrimidine N atoms. The carboxyl-ate group of the 3,5-dinitro-benzoate anion inter-acts with the protonated pyrimidine N atom and the 2-amino group through a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) motif. Two inversion-related pyrimidine rings are linked ...

In the title compound, also known as 3,5-lutidine N-oxide dihydrate, C7H9NO·2H2O, the N-O bond is weakened due to the involvement of the O atom as an acceptor of hydrogen bonds from the two water mol-ecules of crystallization present in the asymmetric unit. Fused R35(10) ring motifs based on O-H⋯O hydrogen bonds form chains in the [010] direction, which are further connected by weak C-H⋯O inter...
