In the crystal structure of the centrosymmetric binuclear title complex, [Ni(2)(C(12)H(8)N(2)O(2)S)(2)(CH(3)OH)(4)], there are inter-molecular O-H⋯O, O-H⋯N and O-H⋯S hydrogen bonds. These help to stabilize the structure and link the mol-ecules, forming a three-dimensional network structure. The Ni(2+) cation exists in a slightly distorted octahedral NiNO(5) coordination environment. The thio-phene rings are disordered over two equivalent conformations with occupancies of 0.881 (3) and 0.119 (3).

The chemistry of copper-dioxygen complexes is relevant to copper enzymes in biology as well as in (ligand)Cu-O (or Cu-O) species utilized in oxidative transformations. For overall energy considerations, as applicable in chemical synthesis, it is beneficial to have an appropriate atom economy; both O-atoms of O are transferred to the product(s). However, examples of such dioxygenase-type chemistry are extremely rare or not well documented.

Article Synopsis
- The Mn complex [Mn(TPDP)(OCPh)](BPh) was synthesized and extensively characterized using multiple analytical techniques to investigate its role as a mimic of class Ib ribonucleotide reductases (RNRs).
- Upon reacting with superoxide anion, the complex formed a peroxido-MnMn complex, showing electronic spectra similar to known peroxido-MnMn compounds, indicating changes in the manganese core structure.
- The new species generated from this reaction showed unique oxidative capabilities, specifically in O-H activation, reflecting some functions of class Ib RNRs but without forming a typical MnMn state.

The title compound, [RuCl(CHP)] or [RuCl(dppm)] (dppm = bis-(di-phenyl-phosphan-yl)methane, CHP) crystallizes as two half-mol-ecules (completed by inversion symmetry) in space group ( = 2), with the Ru atoms occupying inversion centers at 0,0,0 and 1/2, 1/2, 1/2, respectively. The bidentate phosphane ligands occupy equatorial positions while the chlorido ligands complete the distorted octa-hedral coordination spheres at axial positions. The bite angles of the phosphane chelates are similar for the two mol-ecules [(P-Ru-P) = 71.

The title compound, [Fe(CN)(CHN)]·2HO, has been synthesized solvothermally and characterized by single-crystal X-ray diffraction. The octa-hedral iron coordination polyhedron contains two di(pyrimidin-2-yl)amine ligands coordinated in a bidentate fashion, and two monodentate dicyanimido ligands, each coordinated a terminal N atom, with the latter in a orientation. The ligand configuration about the iron atom is chiral, although the compound crystallizes as a racemic mixture: the Fe-N distances (> 2.
