We report discovery of KFe 1.05 Ag 0.88 Te 2 single crystals with semiconducting spin glass ground state. Composition and structure analyses suggest nearly stoichiometric I 4 / mmm space group but allow for the existence of vacancies, absent in long-range semiconducting antiferromagnet KFe 0.85 Ag 1.15 Te 2 . The subtle change in stoichometry in Fe-Ag sublattice changes magnetic ground state but not conductivity, giving further insight into the semiconducting gap mechanism.
