Twelve new ternary intermetallic compounds of light actinide elements from Th to Pu, namely U(4)Tc(7)Si(6), U(4)Tc(7)Ge(6), Np(4)Ru(7)Ge(6), U(2)Tc(3)Si(5), Np(2)Re(3)Si(5), Pu(2)Re(3)Si(5), Th(2)Mo(3)Si(4), U(2)Mo(3)Si(4), U(2)Mo(3)Ge(4), Np(2)Mo(3)Si(4), Np(2)Mo(3)Ge(4) and Pu(2)Mo(3)Si(4), were obtained. The structures of these compounds are discussed as well as some preliminary physical property studies. Magnetic susceptibility measurements show that An(2)Mo(3)(Si or Ge)(4) compounds are paramagnetic at all temperatures studied and that U(4)Tc(7)Si(6) orders antiferromagnetically around 25 K. Mössbauer spectroscopy on Np(4)Ru(7)Ge(6) does not show a magnetic splitting down to 4.2 K.
