Treatment of the complex 2-MeC2Me)2> with an equimolar quantity of M(LL)*2H2O, Na*3H2O, Na, , K, Na, Na or Na> at room temperature in CH2Cl2 affords good yields of the new neutral mixed-ligand complexes 2-MeC2Me)> (1-8). 13C NMR spectroscopy indicates that the but-2-yne is acting as a four-electron donor in these complexes.
