In the title compound, [CoCl(C2H7N)(C3H10N2)2]Cl2, the Co(III) ion has a distorted octa-hedral coordination environment and is surrounded by four N atoms in the equatorial plane, with the other N and Cl atoms occupying the axial positions. The crystal packing is stabilized by N-H⋯Cl hydrogen bonds, forming a layered arrangement parallel to (1-10).

Three 1-(anthracene-9-ylmethyl)-3-isopropyl-imidazol-2-thione Zn(II) halide complexes (1-3) and one 1-(anthracene-9-ylmethyl)-3-isopropyl-imidazol-2-selone Zn(II) dichloride complex (4) were synthesized and characterized. Complexes 2, 3, and 4 exhibited distorted tetrahedral geometries, while complex 1 adopted a regular tetrahedral geometry. All these complexes displayed emission in the crystalline state, with complex 3 emitting in the yellow region and complex 1 and 4 in the blue region, while complex 2 gave a bluish-green emission.

We report the proton-coupled electron transfer (PCET) reactivity of an octahedral Ta(V) aniline complex supported by an acridane-derived redox active NNN pincer ligand. The reversible binding of aniline to a Ta(V) dichloride induces significant coordination-induced bond weakening (CIBW) of the aniline N-H bonds. This enables a rare two-fold hydrogen atom abstraction, resulting in a terminal imido complex and a two-electron oxidation of the NNN pincer ligand, all while maintaining the metal's oxidation state.

The crystal structure of the title compound, hexa-aqua-nickel(II) dichloride-1,4,7,10,13,16-hexa-oxa-cyclo-octa-deca-ne-water (1/2/2), [Ni(HO)]Cl·2CHO·2HO, is reported. The asymmetric unit contains half of the Ni(OH) moiety with a formula of CHClNiO at 105 K and triclinic (1) symmetry. The [Ni(OH)] cation has close to ideal octa-hedral geometry with O-Ni-O bond angles that are within 3° of idealized values.

The isolation and crystalline structure of ,'-di-benzyl-ethyl-enedi-ammonium dichloride, CHN ·2Cl, is reported. This was obtained as an unintended product of an attempted Curtius rearrangement that involved benzyl-amine as one of the reagents and 1,2-di-chloro-ethane as the solvent. Part of a series of reactions of a course-based undergraduate research experience (CURE), this was not the intended reaction outcome.

Micellar catalysis is becoming an increasingly versatile tool to carry out a wide range of organic transformations using water as the reaction medium. The approach was recently found to be effective also in the case of water sensitive organics such as acyl chlorides. This finding is of great relevance for the manufacturing of challenging substrates such as the known iodinated contrast agent iopamidol, requiring the use of aprotic dipolar solvents (DMF, NMP, DMAc) in the key amidation step of an acyl dichloride intermediate with serinol.
