The isothermal section of the phase diagram of ternary Ti-Mn-Sn system has been investigated at 770 K. The existence of new TiMnSn4 ternary compound was established and its crystal structure was determined. TiMnSn4 stannide crystallizes in the Mg2Ni structure type (space group P6(2)22, a=0.55537(1) nm, c=1.40326(2) nm). For the given compound the temperature dependences of electrical resistivity, differential thermopower and magnetic susceptibility were investigated. On the basis of binary Mn3Sn, Ti6Sn5 and Ti3Sn compounds the solid solutions were formed. (C) 2000 Elsevier Science B.V. All rights reserved.
