trans-Bis[bis­(di­phenyl­phosphan­yl)methane-κ²P,P′]di­chlorido­ruthenium(II): a triclinic polymorph

The title compound crystallizes with two different inversion-symmetric mol­ecules having a distorted octa­hedral {P₄Cl₂} coordination environment, and an average P—Ru—P bite angle of 71.1°.

[1,1′-Bi­cyclo­hexa­ne]-1,1′-diol

The title compound is a symmetric diol derived from the pinacol coupling of cyclo­hexa­none. The asymmetric unit contains three complete mol­ecules. Cooperative hydrogen bonding connects the individual mol­ecules into infinite chains propagating along the crystallographic a-axis direction.

2-{3-Methyl-2-[(2Z)-pent-2-en-1-yl]cyclo­pent-2-en-1-yl­idene}-N-phenylhydrazinecarbo­thio­amide

The synthesis, crystal structure and Hirshfeld analysis of the cis-jasmone 4-phenyl­thio­semicarbazone is reported. The mol­ecules are linked into centrosymmetric dimers via pairs of N—H⋯S and C—H⋯S inter­actions, with graph-set motifs (8) and (7). In addition, one N—H⋯N intra­molecular inter­action is observed, with graph-set motif S(5). The crystal structure resembles a zigzag motif when viewed along [010].

(E)-3-(1,3-Di­phenyl-1H-pyrazol-4-yl)-1-(thia­zol-2-yl)prop-2-en-1-one

The crystal structure of a heterocycles containing chalcone is reported.

Methyl 1-(4-fluoro­benz­yl)-1H-indazole-3-carboxyl­ate

The title compound was synthesized by nucleophilic substitution of the indazole N—H hydrogen atom of methyl 1H-indazole-3-carboxyl­ate with 1-(bromo­meth­yl)-4-fluoro­benzene. In the crystal, some hydrogen-bond-like inter­actions are observed.

A second crystalline modification of 2-{3-methyl-2-[(2Z)-pent-2-en-1-yl]cyclo­pent-2-en-1-yl­idene}hydrazinecarbo­thio­amide

The crystal structure and Hirshfeld analysis of a second crystalline modification of the cis-jasmone thio­semicarbazone is reported. The mol­ecular structure matches the asymmetric unit and the mol­ecules are linked into mono-periodic hydrogen-bonded ribbons along [010].

2-{1-[(6R,S)-3,5,5,6,8,8-Hexa­methyl-5,6,7,8-tetra­hydro­naphthalen-2-yl]ethyl­idene}-N-methyl­hydrazinecarbo­thio­amide

The synthesis, crystal structure and Hirshfeld analysis of (R,S)-fixolide 4-methyl­thio­semicarbazone is reported. The compound is disordered over the fixolide fragment and in the crystal, the mol­ecules are linked by H⋯S inter­actions with graph-set motif C(4), forming mono-periodic hydrogen-bonded ribbons along [100].
