Solvent-free synthesis and low-temperature crystal structure of pheno­quinone (the 1:2 p-benzo­quinone–phenol complex)

The solvent-free synthesis of X-ray quality crystals of pheno­quinone (1:2 p-benzo­phenone:phenol cocrystal) is reported, along with its crystal structure re-determined at low temperature. A detailed time-dependent density functional examination of the charge-transfer excitation of pheno­quinone accounting for its color is also provided.

Synthesis and crystal structure of the cubane-like cluster [(Tp*)MoFe₃S₃(μ₃-Cl)(PMe₃)₃](BPh₄)

The title heterometallic single cubane cluster [(Tp*)MoFe₃S₃(μ₃-Cl)(PMe₃)₃](BPh₄) [Tp* = tris­(3,5-di­methyl­pyrazol-1-yl)hydro­borate(1–)] features distinct coordination geometries for the Mo and Fe sites and serves as a typical example in the Mo–Fe–S cluster family with potential applications for the construction of high-nuclearity clusters and synthesis of FeMo-co mimics.

SrZnSi₃O₈, a synthetic member of the feldspar group

Synthetic SrZnSi₃O₈ belongs to the feldspar group with 1/4 of the cationic sites of the tetra­hedral framework fully occupied by Zn²⁺ and 3/4 fully occupied by Si⁴⁺.

Synthesis and crystal structure of a new tetra­nuclear copper(II) complex based on the Schiff base (E)-2-[(2-hy­droxy-5-meth­oxy­benzyl­idene)amino]­benzoic acid

A novel tetra­nuclear Cu²⁺ complex was solvothermally constructed from a salicyl­aldehyde-based Schiff base ligand, which possesses a centrosymmetric framework with two dinuclear Cu²⁺ units; all Cu²⁺ centers adopt a distorted trigonal–bipyramidal coordination geometry. C—H⋯O hydrogen bonds and C—H⋯π inter­actions further consolidate the packing.

Synthesis and structure of 5,5′-(tris­ulfane-1,3-di­yl)bis­(1,3,4-thia­diazol-2-amine)

The title compound contains two 1,3,4-thia­diazol-2-amine moieties bridged by a tris­ulfanediyl group. In the crystal, N—H⋯N hydrogen bonds generate infinite [010] chains.

Synthesis and crystal structure of catena-poly[[aqua­zinc(II)]-bis­[μ₂-4-(phenyl­diazen­yl)benzoato-κ²O:O′]]

In the title compound, the Zn²⁺ ions are coordinated by one water mol­ecule and four oxygen atoms from four different pba⁻ ligands to form a [ZnO₅] trigonal bipyramid. The trigonal bipyramids are bridged by the pba⁻ ligands, extending the structure into chains. The chains are connected through hydrogen-bonding inter­actions.
