1-(4-Chlorophenyl)-3-(2,4-dichlorobenzoyl)thiourea [PDF]

, 2009
The title compound, C14H9Cl3N2OS, has bond lengths and angles which are quite typical for thiourea compounds of this class. The molecule exists in the solid state in its thione form with typical thiourea C=S and C=O bond lengths, as well as shortened C-N

Incommensurate phase in Λ-cobalt (III) sepulchrate trinitrate governed by highly competitive N–H···O and C–H···O hydrogen bond networks [PDF]

, 2021
Phase transitions in molecular crystals are often determined by intermolecular interactions. The cage complex of [Co(C12H30N8)]3+·3NO3– is reported to undergo a disorder–order phase transition at Tc1 ≈ 133 K upon cooling.

N-Cyclo­hexyl-3,4,5-trimethoxy­benzamide [PDF]

, 2009
The 3,5-meth­oxy groups in the title compound, C16H23NO4, are almost coplanar with the aromatic ring, whereas the 4-meth­oxy group is bent out of this plane. The three CH3—O—C—C torsion angles are -1.51 (18), 0.73 (19) and 75.33 (15)°.

4-Nitrophenyl phenyl ether: sheets built from C—H...O and C—H...π(arene) hydrogen bonds [PDF]

, 2003
The racemic title compound, C20H20N4O4, crystallizes with Z' = 2 in the space group P2(1)/c. Each independent molecule exhibits approximate twofold rotation symmetry, but conformational differences between the molecules preclude any higher symmetry.
