Summary
Tetraazaadamantane (taad) reacts with group VI metal hexacarbonyls to give mononuclear (taad)M(CO)5 (M=Cr, Mo and W) derivatives. Mixed ligand metal tricarbonyls,cis- (L-L)(taad)M(CO)3 (L-L=o-phenanthroline or 2,2′-bipyridine; M=Cr and Mo) have also been synthesised. Bromine or iodine reacts with (taad)M(CO)5 (M=Cr and Mo) to give [(taad)M(CO)5X]+X− (X=Br or I). Nitrosyl chloride reacts with (taad)M(CO)5 at room temperature to yieldmer- (taad)M(CO)3NOCl while with the mixed (L-L)(taad)-Mo(CO)3 complex, a mixture of (L-L)Mo(NO)2Cl2 and (L-L)Mo(CO)2NOCl was obtained. An analogous reaction with (L-L)(taad)Cr(CO)3, gave only (L-L)Cr(NO)2Cl2 derivatives. The products have been characterised by elemental analysis, i.r. spectra, conductivity data and magnetic measurements.
