New Ternary Molybdenum Chalcogenides Containing Mo6 and Mo9 Clusters:M2Mo15Se19 (M = Potassium, Ba, Indium, Tl) and

New superconducting MoII compounds M2Mo15X19 (M = K,Ba, In, Tl and X = Se; M = K and X = S) have been found. These materials crystallize in a new structural type containing isolated Mo6X8 and Mo9X11 units. They are superconducting (Tc = 3.32 deg K for K2Mo15S19), and have high initial slopes dHc2/dT...

Description
Summary:New superconducting MoII compounds M2Mo15X19 (M = K,Ba, In, Tl and X = Se; M = K and X = S) have been found. These materials crystallize in a new structural type containing isolated Mo6X8 and Mo9X11 units. They are superconducting (Tc = 3.32 deg K for K2Mo15S19), and have high initial slopes dHc2/dT of the upper critical field.8 refs.--AA
