N2 - The new germanides, Cr4Ge7 with the defect disilicide-type structure and VGe2 with the C40 structure, are synthesized at 4-5.5 GPa and 800-1100°C for 1-3 hr using the belt-type high-pressure apparatus. The relationship between the chemical composition and crystal structure in transition metal disilicides and digermanides is systematically discussed. The following chemical composition sequence accompanied with the change of crystal structure is proposed for the high-pressure synthesis of transition metal (T) silicide (X) and germanide (X) systems: TnXmP Tn′Xm′, (n > n′ and m n < m′ n′ < 2) P TX2.
