The asymmetric unit of the mononuclear cobalt complex, [Co(C11H13O2)2(C6H6N2O)2(H2O)2]·2H2O, contains one half of the complex mol-ecule, one coordinating and one non-coordinating water mol-ecule, one 4-tert-butyl-benzoate (TBB) ligand and one nicotinamide (NA) ligand; the Co atom lies on an inversion centre. All ligands coordinating to the Co atom are(More)
The asymmetric unit of the title compound, [Mn(C7H4NO4)2(C6H6N2O)2(H2O)2], contains one Mn(II) atom, one 4-nitro-benzoate (NB) anion, one nicotinamide (NA) ligand and one water mol-ecule; NA and NB each act as a monodentate ligand. The Mn(II) atom, lying on an inversion centre, is coordinated by four O atoms and two pyridine N atoms in a distorted(More)
The centrosymmetric mol-ecule in the monomeric title cobalt complex, [Co(C10H11O2)2(C10H14N2O)2(H2O)2], contains two water mol-ecules, two 2,4,6-tri-methyl-benzoate (TMB) ligands and two di-ethyl-nicotinamide (DENA) ligands. All ligands coordinate to the Co(II) atom in a monodentate fashion. The four O atoms around the Co(II) atom form a slightly distorted(More)
In the title binuclear Cu(II) complex, [Cu2(C10H11O2)4(C6H6N2O)2], the two Cu(II) cations [Cu⋯Cu = 2.5990 (5) Å] are bridged by four 2,4,6-tri-methyl-benzoate (TMB) anions. The four nearest O atoms around each Cu(II) cation form distorted square-planar arrangements and the distorted square-pyramidal coordinations are completed by the pyridine N atoms of(More)
In the title polymeric compound, [Co(C8H5O3)2(C4H4N2)(H2O)2] n , the Co(II) atom is located on a twofold rotation axis and has a slightly distorted octa-hedral coordination sphere. In the equatorial plane, it is coordinated by two carboxyl-ate O atoms of two symmetry-related monodentate formyl-benzoate anions and by two N atoms of two bridging pyrazine(More)
The asymmetric unit of the title coordination polymer, [Zn(C7H4NO4)2(C6H6N2O)2] n , contains two 4-nitro-benzoate (NB) anions and two nicotinamide (NA) ligands. The Zn(II) atom has a slightly distorted octa-hedral coordination sphere. In the equatorial plane, it is coordinated by three carboxyl-ate O atoms of the NB anions and one O atom of one of the two(More)
The asymmetric unit of the title polymeric compound, [Zn(C8H5O3)2(C4H4N2)(H2O)] n , contains two mol-ecular units. Each unit comprises two 4-formyl-benzoate (FB) anions, one pyrazine mol-ecule and one coordinating water mol-ecule; the FB anions act either as bidentate or as monodentate ligands. The O atoms of the bidentately coordinating FB anions are(More)
In the title complex, [Co(C8H4NO2)2(C6H6N2O)2(H2O)2], the Co(II) atom is located on an inversion centre and is coordinated by two 4-cyano-benzoate (CNB) anions, two nicotinamide (NA) ligands and two water mol-ecules. The four O atoms in the equatorial plane form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral(More)
The asymmetric unit of the title salt, [Zn(C8H4NO2)(C6H6N2O)(H2O)3](C8H4NO2), contains one complex cation and one 4-cyano-benzoate (CNB) counter-anion. The Zn(II) atom in the cation is coordinated by one 4-cyano-benzoate ligand, one nicotinamide (NA) ligand and three water mol-ecules, the CNB anion thereby coordinating in a bidentate O,O'-mode through the(More)
