The title mol-ecule, [Cu(C12H8N2)2(H2O)](NO3)2, is a new polymorph of a compound which up to now has been reported to crystallize space groups in C2/c and Cc. The crystal studied was twinned by non-merohedry (final BASF factor of 0.40043) with the structure being solved and refined in P-1. The Cu(II) atom is coordinated by four N atoms from two(More)
The title compound, {[Co(C10H8N2)2(H2O)2](NO3)2·4H2O} n , (C10H8N2 = 4,4'-bipyridine = 4,4'-bpy) is a layered coordination polymer built up from a cationic square grid extending in (101) enclosing uncoordinating nitrate ions and water mol-ecules. The Co(II) ion has site symmetry 2 and one of the 4,4'-bpy ligands is generated by twofold symmetry [two N atoms(More)
The title compound, C(12)H(16)N(2)O(2), crystallized from toluene with two independent mol-ecules in the asymmetric unit. The dihedral angles between the amide groups and the benzene ring are 60.87 (11) and 54.08 (11)° in one independent molecule and 60.13 (11) and 64.64 (11) in the other. The crystal structure features weak C-H⋯O hydrogen bonds and C-H⋯π(More)
In the title hydrated salt, [NiCl(C10H8N2)2](NO3)·3H2O, the Ni(2+) ion is coordinated by two 2,2'-bipyridyl (2,2'-bpy) ligands and a chloride ion in a trigonal-bipyramidal geometry. The chloride ion occupies an equatorial site and the dihedral angle between the 2,2'-bpy ring systems is 72.02 (6)°. In the crystal, the components are linked by C-H⋯O and O-H⋯O(More)
The title compound, [Na(C(10)H(9.5)N(2)O(2)S(2))(2)(H(2)O)], is a mol-ecular sodium complex with N'-(1,3-dithio-lan-2-yl)-2-hy-droxy-benzohydrazide ligands with the negative charge spread evenly over both, and a water mol-ecule. The Na(I) ion coordination is distorted trigonal-bipyramidal, formed by two N and three O atoms, with the Na(I) ion lying on a(More)
In the title compound, catena-poly[bis[(2,2'-bipyridine-κ(2)N,N')(1,1,3,3-tetracyano-2-ethoxypropenido-κN)copper(II)]-μ4-hexanedioato-κ(6)O(1),O(1'):O(1):O(6),O(6'):O(6)], [Cu2(C9H5N4O)2(C6H8O4)(C10H8N2)2]n, the adipate (hexanedioate) dianion lies across a centre of inversion in the space group P1. The Cu(II) centre adopts a distorted form of axially(More)
The title compound, [Ni(C(5)H(7)O(2))(2)(C(5)H(5)N)(2)]·2H(2)O, crystallizes with two half-mol-ecules in the asymmetric unit. The Ni(II) ion of each unique complex mol-ecule lies on an inversion centre and has an octa-hedral coordination geometry. The crystal structure features weak O-H⋯O hydrogen bonds, which form chains running parallel to the a axis.
