1,1′-(Butane-1,4-diyl)di-1H-imidazole–benzene-1,3,5-triol–water (1/1/1)

The asymmetric unit of the title compound, C10H14N4·C6H6O3·H2O, contains one mol­ecule of benzene-1,3,5-triol, two half-molecules of 1,1′-butane-1,4-diyldi-1H-imidazole (each molecule is centrosymmetric) and one solvent water mol­ecule. In the crystal structure, inter­molecular O—H⋯O and O—H⋯N hydrogen bonds link all mol­ecules into a three-dimensional supra­molecular network

Poly[[[diaqua­cobalt(II)]-bis­[μ2-1,1′-(butane-1,4-di­yl)diimidazole-κ2 N 3:N 3′]] dichloride tetra­hydrate]

In the title compound, {[Co(C10H14N4)2(H2O)2]Cl2·4H2O}n, the CoII atom and the mid-point of the 1,1′-butane-1,4-diyl­diimidazole ligands lie on inversion centers. The CoII atom is six-coordinated in a slightly distorted octa­hedral environment by four N atoms from four different ligands and by two O atoms from the water mol­ecules. The CoII atoms are bridged by the ligands into a (4,4) net. Adjacent nets are linked to the chloride anions and uncoordinated water mol­ecules via O—H⋯Cl and O—H⋯O hydrogen bonds, generating a three-dimensional supra­molecular structure

4-(2,2-Difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile

In the title compound, C12H6F2N2O2, the 2,2-difluoro-1,3-benzodioxole ring system is approximately planar [maximum deviation = 0.012 (2) Å] and its mean plane is twisted with respect to the pyrrole ring, making a dihedral angle of 2.51 (9)°. In the crystal, N—H⋯N hydrogen bonds link the mol­ecules into chains running along the a axis. π–π stacking is also observed between parallel benzene rings of adjacent mol­ecules, the centroid–centroid distance being 3.7527 (13) Å
