Crystal structures and electrochemical properties of nickel(II) complexes with N,N′,N′′,S-tetra­dentate Schiff base ligands

Nickel(II) Schiff base complexes containing thiol­ate S and polyamine N donor atoms exhibit electrocatalytic activity for proton reduction. The piperazine moiety in the Schiff base ligand gives a smaller bite angle, which is effective in reducing the overpotential.

Halogen-bonded zigzag mol­ecular network based upon 1,2-di­iodo­perchloro­benzene and the photoproduct rctt-1,3-bis­(pyridin-4-yl)-2,4-di­phenyl­cyclo­butane

The co-crystal is sustained by I⋯N halogen bonds where the photoproduct acts as a linear linker while the donor behaves as a bent two-connected node within the zigzag chain.

Crystal structures of six 4-(4-nitro­phenyl)­piperazin-1-ium salts

Six piperazinium salts are reported, five of them are hydrated and two crystallized as 2:2 salts. They exhibit asymmetric units of a common 4-nitro­phenyl­piperazine cation and different p-substituent benzoate anions. Their crystal structures mainly pack as chains stabilized by strong N—H⋯O and O—H⋯O hydrogen bonds and other weak inter­actions such as C—H⋯O and C—H⋯π.

The title complexes feature distorted trigonal–planar CuS₂X (X = Br, I) coordination geometries for the metal ions. The presence of the acetone solvent mol­ecule in the iodide complex plays an important role in the packing.

Crystal structure and Hirshfeld surface analysis of 1-(tert-butyl­amino)-3-mesitylpropan-2-ol hemi­hydrate

In the crystal, the two independent mol­ecules are linked through the water mol­ecules by inter­molecular O—H⋯O and O—H⋯N hydrogen bonds, producing chains along the b-axis direction. These chains are linked with neighboring chains parallel to the (103) plane via C—H inter­actions, generating ribbons along the b axis. The van der Waals inter­actions between the strips ensure the stability of mol­ecular packaging.
