In the title compound, [Ni(C(20)H(13)O(5)P)(C(12)H(10)N(2))(H(2)O)](n), the Ni(II) cation is coordinated by three O atoms from two 5-(diphenyl-phosphino-yl)isophthalate anions, two N atoms from two 1,2-bis-(pyridin-4-yl)ethene ligands and one water mol-ecule in a distorted octa-hedral geometry. Both 1,2-bis-(pyridin-4-yl)ethene and 5-(diphenyl-phosphino-yl)iso-phthal-ate bridge the Ni(II) catio...

In the centrosymmetric binuclear title complex, [Ag2(NO3)2(C11H8Cl2N4)2]·2CH3CN, the Ag(I) atom is four-coordinated and exhibits a highly distorted tetrahedral coordination sphere defined by three N atoms from two 1-(3,5-di-chloro-pyridin-2-yl)-2-(pyridin-3-yl-methyl-idene)hy-drazine ligands and one O atom from a nitrate anion. Inter-molecular N-H⋯O hydrogen bonds link the complex mol-ecules, r...

Methyl-ation of [1-hy-droxy-3-(pyridin-2-yl)indolizin-2-yl](pyridin-2-yl)methanone was performed via metalation with potassium tert-butano-late in toluene and a subsequent metathesis reaction with methyl iodide yielded the yellow title compound, C(20)H(15)N(3)O(2). The substituents at the indolizine unit are twisted [the indolizine ring system makes dihedral angles of 34.67 (7) and 77.49 (5)°, ...

In the centrosymmetric title complex, [Fe(C18H12N5)2(H2O)2], the Fe(II) ion, lying on an inversion centre, is coordinated by two N,N'-bidentate 5-(pyridin-2-yl)-3-[4-(pyridin-4-yl)phen-yl]-1H-1,2,4-triazol-1-ide ligands and two water mol-ecules in a trans-FeO2N4 geometry. In the ligand, the triazole ring makes dihedral angles of 5.21 (18) and 6.7 (2)°, respectively, with the adjacent pyridine a...

In the title compound, [Ag2(C6H7N2O2S)2], the Ag(I) atom is coordinated by two N atoms from two N-(pyridin-2-yl)methane-sulfonamidate anions in a slightly bent linear geometry [N-Ag-N = 166.03 (7)°]. The Ag(I) atoms are bridged by the N-(pyridin-2-yl)methane-sulfonamidate anions, forming a centrosymmetric dinuclear mol-ecule, in which the Ag⋯Ag distance is 2.7072 (4) Å.

The photochemistry of the complexes [Fe(N4Py)(CH(3)CN)](ClO(4))(2) (1), where N4Py is 1,1-di(pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)methanamine and [Fe(MeN4Py)(CH(3)CN)](ClO(4))(2) (2), where MeN4Py is 1,1-di(pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)ethanamine, in water, dichloromethane and methanol is described. Under UV or visible irradiation both 1 and 2 undergo enhancement of the rate of ...

Two new Ni(II) complexes involving the ancillary ligand bis[(pyridin-2-yl)methyl]amine (bpma) and two different carboxylate ligands, i.e. homophthalate [hph; systematic name: 2-(2-carboxylatophenyl)acetate] and benzene-1,2,4,5-tetracarboxylate (btc), namely catena-poly[[aqua{bis[(pyridin-2-yl)methyl]amine-κ(3)N,N',N''}nickel(II)]-μ-2-(2-carboxylatophenyl)aceteto-κ(2)O:O'], [Ni(C9H6O4)(C12H13N3)...
