Glycine–D-tartaric acid (1/1)

In the title co-crystal, C₂H₅NO₂·C₄H₆O₆, the gylcine mol­ecule is present in the zwitterion form. In the tartaric acid mol­ecule there is a short intra­molecular O—H...O contact. In the crystal, the tartaric acid mol­ecules are linked via pairs of O—H...O hydrogen bonds, forming inversion dimers. These dimers are linked via a number of O—H...O and N—H...O hydrogen bonds involving the two components, forming a three-dimensional network.

1-Phenyl-2-[4-(trifluoro­meth­yl)phen­yl]-1H-benzimidazole

In the title mol­ecule, C₂₀H₁₃F₃N₂, the benzimidazole unit is close to being planar [maximum deviation = 0.012 (1) Å] and forms dihedral angles of 31.43 (7) and 61.45 (9)° with the 4-(trifluoromethyl)phenyl and 1-phenyl rings, respectively; the dihedral angle between these rings is 60.94 (10)°. In the crystal, C—H...F hydrogen bonds link the mol­ecules into chains along the c-axis direction. The CF₃ group is rotationally disordered with an occupancy ratio of 0.557 (8):0.443 (8) for the F atoms.

2-(4-Meth­oxy­phen­yl)-1-phenyl-1H-benzimidazole

In the title compound, C₂₀H₁₆N₂O, the 1H-benzimidazole ring forms dihedral angles of 48.00 (6) and 64.48 (6)°, respectively with the benzene and phenyl rings, which are inclined to one another by 58.51 (7)°. In the crystal, weak C—H...π inter­actions are the only inter­molecular inter­actions present.
