  • Department of Chemistry, University of Gorakhpur, Gorakhpur-273 001 (L-L)(Pb3E)Mo,CO). (L·L=o-phen or 2,2'-bipy; E=As or Sb) after bromine or iodine oxidation yield [(L-L)(Ph2E)Mo(C0)2XIX(X=Br, I) derivatives. Under similar conditions Ph3P is displaced &rom (L·L)(Ph2 P)Mo(CO). to produce dimeric (L-L)Mo(CO)2X.. Chlorine swept benzene displaces both CO and Ph2P from (L·L)( Ph2P)Mo(C0)2 and only CO from (L-L)(Ph2 E)Mo,CO2). to yield (L-L)MoC14 and [(L-L)(Ph, E)MoCI2]CI2 respectively. Nitrosylation of (L-L)(Ph3E')M(C0)1 (M =Mo, W; E'=P. As, Sb) using NOCI gives a mixture of (L-L)M(N0)2 CI2 and [(L-L)M(CO)2(NO)2CI)CI; while [(L-L)M(C0)2 (N0)2. derivatives are recovered when free NO is used. The complexes have been characterised by elemental analysis, ir, conductivity and magnetic measurements.
