Synthesis and X-ray crystallographic structures of dichloronickel(II) and -palladium(II) complexes containing the biphenyl diamine ligand 6-(2-dimethylaminoethyl)-6,7-dihydro-5-H-dibenz[c,e]azepin
No full textThe diamine N N (N N = 6-(2-dimethylaminoethyl)-6,7-dihydro-5-H-dibenz[c,e]azepin (1)) has been prepared and characterised. It reacts with nickel(II) chloride and bis(benzonitrile)dichloropalladium giving the corresponding complexes MCl2(N N) (M = Ni, 6; Pd, 7) whose crystal structures have been determined. The nickel coordination in complex 6 is distorted tetrahedral, whereas the palladium coordination in complex 7 is square planar. (C) 1999 Elsevier Science S.A. All rights reserved

No full textReactivity of Tris(1-pyrazolyl)methane Towards Ru0 Complexes
No full textBy treating tris(1-pyrazolyl)methane (tpm) with suitably activated [Ru(cod)(cot)] and [Ru(cod)(nap)] (cod = η4-cycloocta-1,5-diene, cot = η6-cycloocta-1,3,5-triene, nap = η6-naphthalene) the (hydrido)RuII species [Ru(N2,N2',C5''-tpm)(cod)H] with cyclometalated tpm was obtained. This complex reacted with chloroform at room temperature to give
[Ru(N2,N2',C5''-tpm)(cod)Cl] and dichloromethane. The coordination and symmetry of the novel complexes were elucidated by 1H and 13C NMR spectroscopy
