Abstract
New silver(I) and copper(I) derivs. [(PR3)x(HnB(Az)m)M] (x=1 or 2, M=Cu or Ag) contg. triorganophosphines PR3 and anionic hydrobis- or hydrotris(azol-1-yl)borates [HnB(Az)m] (Az=azole, n=1, m=3; n=m=2) have been prepd. from AgNO3 or CuCl and PR3 (R=phenyl, benzyl, cyclohexyl, o-, m- and p-tolyl). The interaction between AgX (nitrite, nitrate, trifluoracetate, perchlorate) and bis- or tris-(azolyl)alkanes [HnC(Az)m] (Az=azole, n=1, m=3; n=m=2) also in the presence of ancillary ligands such as triorganophosphines or diphosphines has been also reported. All compds. have been characterized through anal. and spectroscopic measurements (IR, 1H- and 13P-NMR, X-ray) both in the solid and soln. state. Stoichiometries, reactivity, nuclearities and spectroscopic properties of our complexes have been rationalized on the basis of steric and electronic arguments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
