Directionality of electron transfer and long-lived charge separation are of key importance for efficient photocatalytic water splitting. Knowledge of the processes that follow photoexcitation is essential for the optimization of supramolecular assembly designs in order to improve the efficiency of photocatalytic hydrogen generation. Photoinduced intramolecular electron transfer processes within...

In the title compound, {[Ga(2)(C(4)H(4)O(6))(2)(OH)(2)]·2H(2)O}(n), the Ga(III) atom is located on a twofold rotation axis and is six-coordinated by two O atoms from bridging hydroxide groups and four O atoms from two symmetry-related tartrate units in a slightly distorted octa-hedral environment. Each tartrate unit binds to two Ga(III) atoms as a bis-chelating bridging ligand by two pairs of h...

The title complex, [CoNa(CO5P)(H2O)5]n, was obtained by reacting sodium phosphono-formate with cobalt nitrate. The complex contains cobalt(II) and sodium ions, which are bridged by the O atoms of two aqua ligands. The Co(II) ion is octahedrally coordinated by three phosphonoformato ligands (one bi- and the other monodentate) and by two O atoms from the bridging aqua ligands. The sodium cation i...

The asymmetric unit of the title salt, [Ag(C(14)H(14)N(4)O(2))(1.5)](CF(3)SO(3)), comprises a Ag(+) cation, three half-mol-ecules of N,N'-bis-(2-pyridyl-meth-yl)oxalamide (each of which is dis-posed about a centre of inversion) and a trifluoro-methane-sulfonate anion. Distinct coordination modes are found for the bridging ligands, i.e., a μ(2),κ(2)-bridging mode involving pyridine N atoms for o...
