Abstract: The Ba2−xSrxYMoO6 double perovskites with a geometrically frustrated face centered Mo5+ s = 1/2 sublattice have been investigated using neutron powder-diffraction, magnetic-susceptibility, and heat-capacity measure-ments. Reduction in the average A-site radius results in the distortion of the crystal structure from cubic for x = 0 to monoclinic for x = 2 without affecting the Y/Mo inversion (condense into spin singlets as previously observed for Ba2YMoO6, leaving a small fraction of the spins isolated or only weak ferromagnetically coupled to each other.
