We present the synthesis, crystal structure, and physical properties of the new binary phase OMo9Se11. This compound was synthesized at low temperature by silver deinsertion from the ternary orthorhombic compound Ag3.6Mo9Se11. Its crystal structure revealed that both compounds are isostructural (space group Cmcm; a = 11.953 Å, b = 13.069Å, c = 11.039 Å for OMo9Se11 and a = 11.910 Å, b = 13.614 Å, c = 11.679 Å for Ag3.6Mo9Se11). Resistivity and magnetic measurements indicate that the new binary phase becomes a superconductor at 5.5 K while the parent ternary compound shows semiconductor behavior at low temperature. © 1987.
