- Abstract
Pt4Sn4.4Sb7.6 (a = 9.3304(2) Å, space group $Im\,\overline 3 $ ) is an unfilled skutterudite member of the solid solution SnxPt4SnySb 12-x. In contrast to SnxNi4Sn ySb12-y and SnxPt4Sn ySb12-x no Sn could be found in the 2a sites of the Sn/Sb framework. Physical properties have been data for Ni4Sn 3Sb9 and Ni4Sn3.5Sb8.5. Resistivity measurements for Pt4Sn4.4Sb7.6 reveal a temperature dependent crossover from metallic to semiconducting behaviour connected with a corresponding change from negative to positive thermopower at 30 K. Vicker's hardness, thermal expansion and elastic moduli compare well with values of other Sb- investigated in the temperature range from 4.2 K to 800 K and have been compared with based skutterudites.
