The electrochemical oxidation of anodic metal (cobalt and nickel) in acetonitrile solutions of the appropriate pyrimidine- 2-thione derivatives (RpymSH, where R 4-CF3, 4,6-CF3Me, 4,6- MePh, 4,6-CF3Ph, 4,6-Ph2) afforded complexes of composition (M(RpymS)2), M Co, Ni or (Co(RpymS)3). When 2,2-bipyridine (bipy) or 1,10-phenanthroline (phen) was added to the electrolytic cell, adducts of cobalt(II) and nickel(II) compounds with these coli- gands were obtained: (M(RpymS)2bipy) and (M(RpymS)2phen). All of the compounds were characterized by microanalysis, elec- tronic, vibrational spectroscopy and FAB mass spectrometry, and,

Electrochemical Synthesis and Characterization of Cobalt(II), Cobalt(III), and Nickel(II) Complexes with Pyrimidine-2-thionato Ligands

Synthesis, structure and characterisation of a Mn(IV) complex with a potentially tridentate phosphinothiol ligand

Hydrazine complexes [Ru(η5-C5Me5)(NH2NHR1){P(OR)3}L]BPh4 (1–4) [R1 = H, Me, Ph; L = P(OR)3, PPh3; R = Me, Et] were prepared by the reaction of chloro compounds [RuCl(η5-C5Me5){P(OR)3}L] with hydrazines in the presence of NaBPh4. When exposed to air in CH2Cl2 solution, the phenylhydrazine derivatives 1c–4c afforded the sandwich complex [Ru(η5-C5Me5)(η6-C6H6)]BPh4 (5). A reaction path involving the formation of a phenyldiazene complex as an intermediate compound is discussed. The oxidation of hydrazine complexes 1–4 with Pb(OAc)4 at −40 °C yielded diazene derivatives [Ru(η5-C5Me5)(NHNR1){P(OR)3}L]BPh4 (6–9) [R1 = Me, Ph; L = P(OR)3, PPh3]. Aryldiazene complexes [Ru(η5-C5Me5)(NHNAr){P(OR)3}L]BPh4 (7, 9) (Ar = Ph, p-tolyl) were also prepared by allowing hydride [RuH(η5-C5Me5){P(OR)3}L] (10, 11) to react with aryldiazonium salts ArN2+BF4− in CH2Cl2. The complexes were characterised by spectroscopy (IR, 1H, 31P, and 15N NMR) and the X-ray crystal structure of [Ru(η5-C5Me5)(NH2NH2){P(OEt)3}2]BPh4 (2a) and [Ru(η5-C5Me5)(η6-C6H6)]BPh4 (5) was determined.

In [Cd(C 18 H 28 N 6 )Cl 2 ] the Cd atom is located on a twofold rotation axis and is octahedrally coordinated by two Cl atoms [Cd-Cl 2.533 (3) A], two azomethine N atoms [Cd-N(2) 2.45 (1) A] and two amino N atoms [Cd-N(1) 2.458 (9) A] in a distorted geometry. The pyrrole N atoms are not coordinated
