Substantial contact contribution to the isotropic shifts have been observed in variable temperature H n.m.r. studies of low-spin complexes Co(BAE) and Co(F3BAE) (18).  

The base adducts M(hfa)2(py)2 M(hfa)2phen and M(hfa)2bipy (M = Co, Ni, or Cu Hhfa = hexafluoroacetylacetone) have been prepared and all have a cis-octahedral configuration except for the Ni(hfa)2(py)2 complex. The synthesis of cobalt(ii) and nickel(ii) complexes of some substituted azomethines (19) has been reported.  

The structure of [Co(amben)] (79) has been determined. The cobalt atom 

The high-spin tetrahedral compound Co(OCgH4CONH2)2 has been prepared and i.r. data indicate that the ligands chelate via both oxygen atoms.

Other N-donor ligands. Nitrile complexes such as [RuX2(RCN)4] (R = Me, Et, Prn, Pr , Ph, or PhCH2 X = Cl or Br) have been prepared from RuC13,3H20

PrnNH2, Bu NH2, or Bu NH2) has been prepared via route (7),39 which is similar to the method previously employed390 to synthesize the analogous hexa-ammine. 

Subsequent reaction of these complexes with benzonitrile yielded the useful products [RuL5(PhCN)]X2. 

Two papers report the isolation of arylazoruthenium complexes.40,41 Reaction of ArNH2 (Ar = p-MeC6H4 or p-MeOC6H4) with the co-ordinated nitrosyl ligand in [RuCl(NO)(bipy)2]2+ yielded complexes (7).40 The position of the N-N 

The bis(biuretato)cobalt(iii) complex K[Co(3-propbi)2],2(l-propbiH2) (3-propbi = NH CO NPr CONH , l-propbiH2 = Pr NH CO NH CO NHPr ) is paramagnetic (p = 3.51 BM between 120 and 300 K, p = 3.41 BM in DMSO at room temperature). An X-ray structural study shows the anion to have planar co-ordination via the deprotonated amide nitrogen atoms of the

Other N-donor ligands. Decomposition of the iron(ii) complex of iV-(2-pyridyl-methylene)-4-methylaniline with edta provides a convenient route to the parent Schiff base (57) however, decomposition in an acetone-water mixture yields... 

Other N-donor ligands. The cation of [Co(py)4C03]C104,H20 has been found to have a distorted octahedral structure, the distortion being due to strain in the four-membered chelate ring (O—C —O angle = 69.3°) and steric hinder-...

Other N-donor ligands. The reaction between [Ru(NH3)j(H20)] and hydra-zoic acid has been shown to give rapidly one mole of nitrogen and 0.5 moles of both [Ru(NH3)5] and [Ru(NH3)5(H20)] . The proposed mechanism [equation (4)-( 7)] involves Ru—N bond formation prior to N—cleavage in the azide group. In contrast to similar ruthenium(m) nitrenes the species... 

Other N-donor ligands. Unlike ruthenium chemistry, few osmium nitrosylamines are known. The complexes [Os(NH3)s(NO)]l3 and [OsI(NH3)4(NO)]l2 have now been prepared by treating [Os(NH3)5l]l2 with NO, and their properties compared with analogous ruthenium complexes. The reactions of [0s(NH3)5(N0)]X3,H20 (X = Cl, Br, or I) are summarized in Scheme 5. 

Recently an attempt was made [45] to use palladium(II) cationic complexes bearing ADCs, further stabilized by pyridine or other N-donor ligands (E1-E7 Fig. 11.4), as catalysts for the cross-coupling.
