  Picolinate with the carboxylate group in the ortho -position chelated the platinum(II) atom by a ( N , O ) chelation mode resulting in the formation of a cationic complex. However, nicotinate and isonicotinate with the carboxylate group in meta - and para -positions, respectively, did not chelate but coordinated to the platinum(II) atom through their nitrogen atoms resulting in the formation of zwitterionic

  Reactions of aqueous vanadium(II) sulphate with pyridine-2-carboxylate (and other carboxylic acids) and 3-pyridinesulphonate (pySO3) salts have been investigated, as well as the reaction of the products with pyridine. Two of the products have been structurally characterized by X-ray crystallography. An aquo carboxylato compound, [V(Pic)2(H2O)2] . 2H2O (I) (Pic = anion of picolinic acid), crystallizes in the monoclinic space group P2(1)/n with a = 9.930(2), b = 5.169(1), c = 14.543(2) angstrom, beta = 90.35(2)-degrees, V = 746.1(2) angstrom3 and Z = 2. Extensive hydrogen bonding in the structure provides sufficient protection to the metal centre to make the crystals relatively stable in air. The pyridine adduct V(pySO3)2(py)4 (II) possesses a molecular structure and crystallizes in the monoclinic space group C2/c with a = 17.033(4), b = 11.218(4), c = 17.396(4) angstrom, beta = 110.05(2)-degrees, V = 3122(2) angstrom3 and Z = 4. Both compounds exemplify the facile formation of bonds between vanadium(II) and nitrogen-containing ligands.
