 Title    Electrochemical Syntheses of Pyrimidine-2-thiolato Complexes of Nickel(II) Crystal and Molecular Structure of 2,2 -Bipyridine-bis(pyrimidine-2-thiolato)nickel(II) Monohydrate+  
 Abstract    The electrochemical oxidation o f nickel in pyrimidine-2-thione (pym tH) solution yields a com pound o f formula [Ni(pymt)-,]. When pyridine (py), 2,2'-bipyridine (bipy) or 1,10-phenan­ throline (phen) are added to the solution phase, the product obtained is a complex [Ni(pym t)2py2] or [Ni(pym t)2L] (L = bipy or phen). The crystal structure o f [Ni(pym t)2bipy] • H 20 is monoclinic, space group P 2,/c, with a = 726.6(2), b = 1586.2(2), c =

 Title    Direct Electrochemical Synthesis of Pyrimidine-2-thionato Complexes of Zinc(II) and Cadmium(II): The Crystal Structure of (l,10-Phenanthroline)bis(pyrimidine-2-thionato)cadmium(II)  
 Abstract    Zn(pymt)2 and Cd(pymt)2 complexes have been obtained by electrochemical oxidation o f anodic zinc or cadmium in acetonitrile solutions o f pyrimidine-2-thione (Hpymt). W hen 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) was added to the electrochemical cell, the ad-ducts [M (pymt)2(bipy)], or [M(pymt)2(phen)] (M = Zn or Cd) were obtained. Crystals o f [Cd(pymt)2phen] are orthorhombic, with a = 9.882(2), b = 12.491(1), c = 16.513(2)A, space group P 2,2,2, and Z = 4. The cadmium atom has distorted octahedral geometry, and one ni­ trogen atom o f each pyrimidine-2-thiolato ligand is not coordinated.
