    In the title compound, C24H18Cl3NO3, the tetrahydrofuran rings adopt envelope conformations. In the crystal, C-H center dot center dot center dot O hydrogen bonds connect molecules, generating layers parallel to the (001) plane. These layers are connected along the c-axis direction by C-H center dot center dot center dot pi interactions. The packing is further stabilized by interlayer van der Waals and interhalogen interactions. The most important contributions to the surface contacts are from H center dot center dot center dot H (36.8%), Cl center dot center dot center dot H/H center dot center dot center dot Cl (26.6%), C center dot center dot center dot H/H center dot center dot center dot C (18.8%) and O center dot center dot center dot H/H center dot center dot center dot O (11.3%) interactions, as concluded from a Hirshfeld surface analysis.

    Crystal structure and Hirshfeld surface analysis of dimethyl 5-[2-(2,4,6-trioxo-1,3-diazinan-5-yl-idene)hydrazin-1-yl]benzene-1,3-dicarboxylate 0.124-hydrate

    In the crystal, the whole molecule of the title compound, C14H12N4O7·0.224H2O, is nearly planar with a maximum deviation from the least-squares plane of 0.352?(1)?Å. The molecular conformation is stabilized by an intramolecular N—H?O hydrogen bond, generating an S(6) ring motif. In the crystal, molecules are linked by centrosymmetric pairs of N—H?O hydrogen bonds, forming ribbons along the c-axis direction. These ribbons connected by van der Waals contacts, forming sheets parallel to the ac plane. There are also intermolecular van der Waals contacts and and C—H?? interactions between the sheets. A Hirshfeld surface analysis indicates that the most prevalent interactions are O?H/H?O (41.2%), H?H (19.2%), C?H/H?C (12.2%) and C?O/ O?C (8.4%).

    The title compound, [RuCl2(C33H43N3O)], is an example of a new generation of N,N-dialkyl ruthenium catalysts with an N—Ru coordination bond as part of a six-membered chelate ring. The Ru atom has an Addison ? parameter of 0.244, which indicates a geometry intermediate between square-based pyramidal and trigonal–bipyramidal. The complex shows the usual trans arrangement of the two chlorides, with Ru—Cl bond lengths of 2.3515?(8) and 2.379?(7)?Å, and a Cl—Ru—Cl angle of 158.02?(3)°. One of the chlorine atoms and the atoms of the 2-methoxy-N-methyl-N-[(2-methylphenyl)methyl]ethane-1-amine group of the title complex display disorder over two positions in a 0.889?(2): 0.111?(2) ratio.
