Accepted 20 February 2019


The title mol­ecule comprises fluoro­phenyl (A), methyl­triazolyl (B), methyl­triazolyl (C) and tolyl (D) rings. The twist angles between the planes through neighbouring ring pairs A/B, B/C and C/D are 45.0 (1), 9.4 (1) and 43.2 (1)°, respectively.

N′-[5-Acetyl-3-(4-bromo­phen­yl)-2,3-di­hydro-1,3,4-thia­diazol-2-yl­idene]-5-(1H-indol-3-yl)-1-phenyl-1H-pyrazole-3-carbohydrazide di­methyl­formamide monosolvate

In the crystal, the mol­ecules are related by c-glide symmetry to form columns parallel to [001] which are linked by inter­molecular N—H⋯O, C—H⋯O and C—H⋯Br contacts.

Accepted 15 February 2019

The sodium chloride complex catena-poly[[{μ3-2-[bis­(2-hy­droxy­eth­yl)amino]­ethan-1-ol}sodium] chloride], N(CH2CH2OH)3·NaCl

The chloride anion in the polymeric title salt [Na(N(CH2CH2OH)3)]Cl controls the supra­molecular structure in such a way that infinite polymeric chains formed by coordination of the sodium cation by the amino alcohol are linked via hydrogen bridges, giving a two-dimensional network structure.

5,8,13,13-Tetra­chloro-13H-dibenzo[a,i]fluorene cyclo­hexane hemisolvate

Planar penta­cyclic chloro­aromatics are arranged in parallel layers, with the chlorine atoms protruding from these planes. Channels orthogonal to these layers are filled with disordered cyclo­hexane mol­ecules.

Accepted 15 February 2019


The title compound comprises phenyl (A), triazolyl (B), thia­zolyl (C), pyrazoyl (D), tolyl (E) and fluorophenyl (F) rings, with twist angles between neighbouring ring pairs A/B, B/C, C/D, D/E and D/F of 64.6 (1), 11.7 (2), 23.5 (2), 8.2 (2) and 73.3 (1)°, respectively. A short intra­molecular C—H⋯N contact and a weak inter­molecular C—H⋯π inter­action occur.

Accepted 11 February 2019


The title compound crystallizes in space group P212121. The phenyl rings have a twisted conformation.

Accepted 10 February 2019


In the crystal, inversion-related pairs of mol­ecules are linked by weak C—H⋯N inter­actions, forming dimers. These dimers inter­act through π–π contacts between the thia­zolyl units [centroid-to-centroid distance = 3.826 (1) Å], forming chains along [010].
