2-(Benzotriazol-1-yl)-2-(α-hydroxybenzyl)-N-phenylthioacrylamide

In the title compound, C₂₁H₁₆N₄OS, the dihedral angles between the planes of the benzotriazole and N-phenyl rings and the plane of the atoms that link these two rings are 79.56 (6) and 59.02 (5)°, respectively, while that between the two benzene rings is 64.12 (6)°. There are some inter- and intramolecular interactions in the crystal structure.

1-(4-Hydroxy­phenyl)-3-(1H-1,2,4-triazol-1-yl)propan-1-one

In the title compound, C₁₁H₁₁N₃O₂, the dihedral angles made by the planes of the triazole and benzene rings with the plane through the OC₃ atoms of the ketone group are 72.87 (4) and 7.10 (3)°, respectively. There are some intermolecular interactions in the crystal structure, which contribute to the stability.

Diiso­thio­cyanato­bis(2-methyl-1H-imidazole)­cobalt(II)

In the title compound, [Co(NCS)₂(C₄H₆N₂)₂], each cobalt(II) ion is coordinated by two N atoms from two 2-methyl-1H-imidazole ligands and two N atoms from two iso­thio­cyanate groups. The Co atom lies on a mirror plane and adopts a slightly distorted tetrahedral coordination. The molecular structure and packing are stabilized by intramolecular and intermolecular hydrogen-bond interactions.

Diisothio­cyanato­tetra­kis­(1-meth­yl-1H-imidazole-κN³)nickel(II)

The structure of the title compound, [Ni(NCS)₂(C₄H₆N₂)₄], consists of isolated mol­ecules of [Ni(NCS)₂(Mim)₄] (Mim = 1-methyl­imidazole), which contain a compressed octa­hedral NiN₆ chromophore. The NCS⁻ anions are trans and four N atoms from the 1-methyl­imidazole ligands define the equatorial plane. The mean Ni—N(Mim) and Ni—N(NCS) distances are 2.115 (4) and 2.087 (4) Å, respectively.
