- Аннотация: When searching for new analogues of Millon's phases, new compounds Hg(13)As(8)(ZnCl(4))(4) (I), Hg(23)As(12)(ZnBr(4))(6) (II), and (Hg(2)As)(2)ZnI(4) (III) were found. Phases I and 11 were synthesized during the two-temperature annealing. Phase III is prepared by a standard ampule procedure. Crystal structures I and 11 were determined by X-ray single-crystal diffraction. The crystals of I are orthorhombic, space group Pnam, a = 25.326(6) angstrom, b = 13.656(2) angstrom, c = 12.148(2) angstrom, Z = 4; the crystals of II are hexagonal, space group P62m, a = 13.462(2) angstrom, c = 12.175(2) angstrom, Z = 1. The crystals of III are monoclinic, space group P2(1) or P2(1)/m, a = 7.977(9) angstrom, b = 12.954(4) angstrom, c = 8.00(1) angstrom, beta = 119.9(1)degrees; the compound seems to be isostructural to (Hg(2)P)(2)ZnI(4), a phosphorus analogue of Millon's phases. All three structures contain three-dimensional charged frameworks of different structures formed by mercury and arsenic atoms and tetrahedral ZnX(4)(2-) anions arranged in the cavities. Structures I-III are compared to one another and to the structures of known phosphorus analogues of Millon's phases.
