We describe a series of air-stable NiIII complexes supported by simple, robust naphthyridine-based ligand. Access to the high-valent oxidation state is enabled CF3 ligands on nickel, while naphthyridine exhibits either monodentate or bidentate coordination mode that depends and sterics, enables facile aerobic NiII NiIII. These act as efficient catalysts for photoinduced C(sp2)−H bond trifluorom...

In each of the two mol-ecules in the asymmetric unit of the title compound, [Ni(C(13)H(18)NO(4)S)(2)(C(5)H(5)N)(2)(H(2)O)], the geometry of the Ni(2+) ion is an extremely distorted trans-NiN(2)O(4) octa-hedron, arising from its coordination by one water mol-ecule, two pyridine mol-ecules, and one O-monodentate and one O,O'-bidentate deprotonated N-p-tolysulfonyl-l-leucine ligand. In the crystal...

In the title compound, [Mn(C(10)H(7)N(6))(2)(H(2)O)(4)]·2H(2)O, the complex unit comprises an Mn(2+) ion, coordinated by two imidazole N atoms from cis-related monodentate 5-[4-(imidazol-1-yl)phen-yl]tetra-zolide ligands and four water mol-ecules, together with two water mol-ecules of solvation. The Mn(2+) ion lies on a twofold rotation axis and has a slightly distorted octa-hedral geometry. Th...

In the title coordination polymer, {[Sr(C(4)HO(4))(2)(H(2)O)(5)]·0.5H(2)O}(n), the Sr(2+) ion is coordinated by three monodentate hydrogensquarate (hsq) anions and six aqua ligands in a distorted SrO(9) monocapped square-anti-prismatic geometry. The hsq anions and water mol-ecules bridge the metal ions into infinite sheets lying parallel to (100). The O atom of the uncoordinated water mol-ecule...

The title compound, [Pd(C(2)H(3)OS(2))(2)(C(18)H(15)P)], features a palladium complex with a triphenyl-phosphane ligand and two xanthate ligands, one of them coordinates in a bidentate and the other in a monodentate fashion, giving rise to a slightly distorted square-planar coordination of the Pd(II) ion. As a result of this difference in the coordination modes, the C-S bond lengths are differe...

The polymeric structure of the title compound, {[Ca2(C6H2N2O4)2(H2O)6]·2H2O} n , is built up of mol-ecular layers composed of Ca(II) ions bridged by both ligand N and O atoms with one of the O atoms being bis-monodentate. Two adjacent Ca(II) ions are bridged by these O atoms, forming a centrosymmetric dimer which is the building unit of the structure. The dimers are nodes of a cross-linked mol-...

In the title compound, [Cu(C11H10N3O)2(C8H4O5)2]·4H2O, the Cu(II) ion, located on a crystallographic inversion center, is coordinated in a square-planar environment by two trans-O atoms belonging to two monodentate 5-hy-droxy-isophthalate (hip) dianions and two trans nicotinamide pyridyl N-donor atoms from monodentate protonated pendant N-(pyridin-4-yl)nicotinamide (4-pnaH) ligands. The protona...

In the title complex, [Co(C(8)H(7)O(3))(2)(C(6)H(6)N(2)O)(H(2)O)(2)], the Co(II) atom is coordinated by three O atoms from two 4-meth-oxy-benzoate ligands, which act in different modes, viz. monodentate and bidentate, two water mol-ecules and one N atom of the isonicotinamide ligand in a distorted octa-hedral geometry. The monodentate-coordinated carboxyl-ate group is involved in an intra-molec...

The title compound, [Co(C(7)H(5)O(2))(2)(C(12)H(16)N(3)O(2))(2)(H(2)O)(2)], was obtained from a conventional solvent evaporation method. The complex mol-ecule is centrosymmetric, so pairs of equivalent ligands lie trans to each other in a slightly distorted octa-hedral CoN(2)O(4) geometry. The Co(II) ion is coordinated by the pyridine N atoms from NITpPy ligands [NITpPy is 4,4,5,5-tetra-methyl-...
