摘要：
Cu2Mo6Cl14 (I), Cu2Mo6Br14 (II) and Cu2Mo6I14 (III) were synthesized by thermal treatment of corresponding mixtures of copper(I) and molybdenum(II) halides. The crystal structures were determined by single crystal X-ray analyses. I and II show isotypism, cubic, Pn(3) over bar (no. 201, sec. setting), Z = 4, I: a = 12.772(3) Angstrom, II: a = 13.350(2) Angstrom. III shows a new structural type, orthorhombic, Pbca (No. 61), Z = 4, a = 16.058(3) Angstrom, b = 10.643(2) Angstrom, c = 16.963(3) Angstrom. Trigonal planar CuX(3) units were found in I-III. Structural behaviour relations are discussed, especially with regard to ionic conductivity.
