Sahin, Onur; Büyükgüngör, Orhan; Kose, Dursun Ali; Zumreoglu-Karan, Birgul; Necefoglu, Hacali (Int Union Crystallography, 2006)The Co-II ion in the title complex {[ Co(C5H2N2O4)( H2O)(3)] -1.72H(2)O} n, has a distorted octahedral coordination geometry comprised of three water ligands, one deprotonated pyrimidine N atom and an adjacent carboxylate ... -
Synthesis and characterization of transition metal-vitamin B13 complexes mixed with a co-vitamin
Kose, Dursun Ali; Zumreoglu-Karan, Birgul; Unaleroglu, Canan; Sahin, Onur; Büyükgüngör, Orhan (Taylor & Francis Ltd, 2006)The synthesis and structural characterization of mixed vitamin-metal complexes are reported. A complex bearing two vitamins (B3 and B13) on the same metal centre, nicotinamide(orotato) nickel(II) pentahydrate, has been ... -
Transition metal(II) complexes of vitamin B13 with monodentate orotate(1-) ligands
Kose, Dursun Ali; Zumreoglu-Karan, Birgul; Sahin, Onur; Büyükgüngör, Orhan (Elsevier Science Bv, 2006)The formation of bisorotate(1-) complexes of the type [M(C5H3N2O4)(2)(H2O)(4)] center dot nH(2)O (M = Co, Ni, Zn and n = 2, 4) was achieved by the reaction of ammonium orotate with the corresponding M(II) ions. The crystal ...
