The *2*3*2Th(*4*8Ca, 5n)*2*7*5Ds and *2*3*8U(*4*0Ar, 5n)*2*7*3Ds reactions have been studied at the gas-filled separator DGFRS-2 at the Superheavy Element Factory at Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research. For the first time, a new isotope *2*7*5Ds with a half-life of 0.43&sup(+0.29)&sub(-0.12)ms and α-particle energy of 11.20±0.02 MeV was synthesized in the *4*8Ca-induced reaction with the actinide nucleus and identified by measuring correlated α decays ending in known nuclei. The decay properties of nuclei originating from *2*7*3Ds and *2*7*5Ds are compared with theoretical calculations and decay schemes are proposed. The cross sections of the *2*3*2Th(*4*8Ca, 5n)*2*7*5Ds reaction of 0.11&sup(+0.46)&sub(-0.09) and 0.34&sup(+0.59)&sub(-0.16)pb were measured at excitation energies of the *2*8*0Ds compound nucleus E&sup(* )=51 and 56 MeV, respectively. The cross section of the 5n-evaporation channel of the *2*3*8U+*4*0Ar reaction at E&sup(* )=49 MeV of 0.18&sup(+0.44)&sub(-0.12)pb turned out to be comparable to that for *2*7*5Ds at close excitation energy.
