In the title compound, C(10)H(16)N(2)O·H(2)O, the cyclo-hexane ring is in a chair conformation and its least-squares plane makes a dihedral angle of 53.68 (5)° with the approximately planar pyrazole ring [maximum deviation = 0.034 (1) Å]. Pairs of inter-molecular N-H⋯O hydrogen bonds form inversion dimers between neighbouring pyrazolone mol-ecules, generating R(2) (2)(8) ring motifs. The pyrazolone and water mol-ecules are further linked by inter-molecular N-H⋯O, C-H⋯O and O-H⋯O hydrogen bonds into two-dimensional sheets parallel to the bc plane.

The title compounds, CHO ( and ), are tetra-cyclic benzoates composed of a taxane ring with a fused dioxolane ring as the core skeleton. In compound , the five-membered dioxolane ring is essentially planar while the two cyclo-hexane rings and the cyclo-octane ring adopt chair and chair-chair forms, respectively, and there are three intra-molecular H⋯H short contacts. The corresponding ring conformations in are similar; however, one intra-molecular C-H⋯O inter-action and two H⋯H short contacts are observed, and the benzoyl and meth-oxy-methyl groups show orientational disorder.

The title compound, [Cu(CHO)(CHN)], crystallizes in the ortho-rhom-bic space group . In the crystal structure, the Cu ion is coordinated by two acetyl-acetonate ligands and one 2-amino-1-methyl-1-benzimidazole ligand. The crystal structure features intra-molecular N-H⋯O and inter-molecular N-H⋯O hydrogen bonds, which contribute to the overall cohesion of the crystal.

The crystal structure of luliconazole {LCZ; CHClNS; systematic name: ()-[(4)-4-(2,4-di-chloro-phen-yl)-1,3-di-thio-lan-2-yl-idene](1-imidazol-1-yl)aceto-nitrile} is reported. In the mol-ecule of the title compound, the di-thiol-ane ring adopts an envelope conformation, while the di-chloro-phenyl ring exhibits disorder. In the crystal packing of luliconazole, only two inter-molecular C-H⋯N hydrogen bonds are observed.

A novel coordination compound, [Co()(HO)], was synthesized from aqueous solutions of Co(NO) and the ligand 2-[(5-methyl-1,3,4-thia-diazol-2-yl)sulfan-yl]acetic acid (H, CHNOS). In the monoclinic crystals (space group 2/), the cobalt(II) ion is located about a centre of symmetry and is octa-hedrally coordinated by two anions in a monodentate fashion through carboxyl O atoms and by four water mol-ecules. A relatively strong hydrogen bond between one of the water mol-ecules and the non-coordinating carboxyl-ate O atom consolidates the conformation.

The asymmetric unit of the title compound, CHN·Br·CFI, contains one 2,2,6,6 tetra-methyl-piperidine-1-ium cation, one 1,2,3,4-tetra-fluoro-5,6-di-iodo-benzene mol-ecule, and one uncoordinated bromide anion. In the crystal, the bromide anions link the 2,2,6,6-tetra-methyl-piperidine mol-ecules by inter-molecular C-H⋯Br and N-H⋯Br hydrogen bonds, leading to dimers, with the coplanar 1,2,3,4-tetra-fluoro-5,6-di-iodo-benzene mol-ecules filling the space between them. There is a π-π interaction between the almost parallel benzene rings [dihedral angle = 10.
