چکیده

The title salt, C8H12NO(+)·Br(-)·H2O, is isomorphous with the chloride analogue [Seethalakshmi et al. (2013). Acta Cryst. E69, o835-o836]. In the solid state, the cations, anions and water mol-ecules are inter-linked by a network of O-H⋯O, O-H⋯Br and C-H⋯Br inter-actions. The water mol-ecule makes two O-H⋯Br hydrogen bonds, generating [010] zigzag chains of alternating water mol-ecules and bromide anions. The cation is involved in two inter-molecular C-H⋯Cl inter-actions in the chloride salt, whereas three inter-molecular C-H⋯Br inter-actions are observed in the title bromide salt. This additional inter-molecular C-H⋯Br inter-action links the adjacent water and bromide zigzag chains via cationic mol-ecules. In addition, weak π-π stacking inter-actions are observed between pyridinium rings [centroid-centroid distance = 3.5664 (13) Å].

4-Hy­droxy-1,2,6-tri­methyl­pyridinium chloride monohydrate

In the crystal of the title hydrated mol-ecular salt, C8H12NO(+)·Cl(-)·H2O, the water mol-ecule makes two O-H⋯Cl hydrogen bonds, generating [010] zigzag chains of alternating water mol-ecules and chloride ions. The cation is bonded to the chain by an O-H⋯O hydrogen bond and two weak C-H⋯Cl inter-actions. Weak aromatic π-π stacking [centroid-centroid separation = 3.5175 (15) Å] occurs between th...

The title structure, {[Ba(0.71)Sr(1.29)(C(4)HO(4))(4)(H(2)O)(10)]·H(2)O}(n), is built from dimers of edge-sharing monocapped square anti-prisms [(Ba/Sr)O(3)(H(2)O)(6)], in which barium and strontium are statistically disordered [ratio 0.353 (8):0.647 (8)] on the same crystallographic site. Such dimers are connected via bidentate hydrogen squarate groups [HC(4)O(4)](-), leading to chains that pr...

In structure of the title compound ammonium ferulate monohydrate, NH(4) (+)·C(10)H(9)O(4) (-)·H(2)O, O-H⋯O and N-H⋯O hydrogen bonds link the ammonium cations, ferulate anions and water mol-ecules into a three-dimensional array. The ferulate anion is approximately planar, with a maximum deviation of 0.307 (2) Å.

2-Cyano-N′-(5-hy­droxy-2-nitro­benzyl­idene)acetohydrazide monohydrate

The title compound, C(10)H(8)N(4)O(4)·H(2)O, was obtained by the reaction of 5-hy-droxy-2-nitro-benzaldehyde with cyano-acetohydrazide in methanol. The non-H atoms of the hydrazone molecule are approximately coplanar, with a mean deviation from the least-squares plane of 0.056 Å. In the crystal, mol-ecules are linked by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, generating a three-dimensional network.

In the title compound, C(15)H(13)BrN(2)O(3)·H(2)O, the dihedral angle between the two benzene rings is 13.92 (6)°. The meth-oxy group of the 4-hy-droxy-3-meth-oxy-phenyl is almost coplanar with its bound benzene ring, as seen by the C(meth-yl)-O-C-C torsion angle of -0.35 (16)°. In the crystal, mol-ecules are linked into a three-dimensional network by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds and a...
