Triply ferrocene-bridged boroxine cyclophane.

Mild solvothermal dehydration of 1,1'-ferrocenediboronic acid produces a triply ferrocene-bridged boroxine cyclophane. Its crystal structure reveals a rigid trigonal prism that presents a minimal boroxine-based covalent organic polyhedron (COP).

1,8-Bis(tos­yloxy)-9,10-anthraquinone

In the crystal structure of the title compound, C(28)H(20)O(8)S(2), adjacent anthracene skeletons are parallel or inclined at an angle of 20.6 (1)°. In the mol-ecular structure, the mean plane of the anthracene skeleton makes dihedral angles of 49.6 (1) and 76.8 (1)° with the tosyl rings, and the two terminal benzene rings are oriented at an angle of 74.5 (1)° with respect to each other. The cr...

A chiral dumbbell shaped bis(fullerene) oligoelectrolyte.

The first icosacationic bis(fullerene) whose water solubility is provided by twenty peripheral ammonium groups has a rigid, almost cylindrical shape and was synthesized by connecting two fullerene cores with a chiral cyclo-bis(malonate), followed by the regioselective addition of ten amino-terminated malonates into the octahedral positions of the fullerene moieties and subsequent cleavage of th...

Facile synthesis of a chiral urea bridged bisoxazoline ligand and structural characterization of its bis-copper(II)-chloride complex.

A facile synthesis of a new bisoxazoline ligand is described. This ligand contains a urea bridging unit and is capable of stabilizing bimetallic complexes. An X-ray crystal structure of a bis-copper complex is reported.

Mechanism of Water Oxidation Catalyzed by a Dinuclear Ruthenium Complex Bridged by Anthraquinone

We synthesized 1,8-bis(2,2′:6′,2”-terpyrid-4′-yl)anthraquinone (btpyaq) as a new dimerizing ligand and determined its single crystal structure by X-ray analysis. The dinuclear Ruthenium complex [Ru2(μ-Cl)(bpy)2(btpyaq)](BF4)3 ([3](BF4)3, bpy = 2,2′-bipyridine) was used as a catalyst for water oxidation to oxygen with (NH4)2[Ce(NO3)6] as the oxidant (turnover numbers = 248). The initial reaction...
