- Аннотация: Two new supramolecular complexes, [Hg6As4](CuBr3)(2) (1) and [Hg6As4](CuCl3)(2) (2), have been synthesized and their crystal structures have been determined. Compound I crystallizes in the monoclinic system, space group I2/a (No. 15), with the unit cell dimensions a = 14.884(3), b = 9.358(2), c = 20.413(4) angstrom, beta = 92.88(3)degrees, and Z = 6. The crystal structure is comprised of the three-dimensional (3)(infinity)[Hg6As4](4+) polycationic framework hosting one-dimensional 6-step helical (1)(infinity)(CuBr3)(2-) guest chains built of the [CuBr4] tetrahedra sharing two of their vertexes. The complex 2 exhibits a distorted variant of the same type of crystal structure (space group I2/a, a = 14.690(l), b = 9.1851(7), c = 20.285(1) angstrom, beta = 92.170(1), and Z = 6) that is characterized by a multifarious positioning of the guest anions in the cavities of the perfectly ordered (3)(infinity) [Hg6As4](4+) host framework. Structures of the title supramolecular assemblies and the previously reported silver-containing analogue [Hg6As4](AgCl3)(2) are discussed taking into account the principles of host guest complementarity.
