摘要

Formation of the novel compound [K-36(mu(6)-Cl)(2)(H2O)(11)(MeOH)(32)][SnSe4][Co-4(mu(4)-Se)(SnSe4)(4)](3) (2) was achieved by variation of the crystallization conditions that recently enabled synthesis of the quaternary compound [K-22(H2O)(17)(MeOH)(8)][SnSe4](3)[Co-4(mu(4)-Se)(SnSe4)(4)] (1) by reaction of K-4[SnSe4] with [Co(en)(3)]Cl-3 in a methanol/water mixture (19:1). The crystal structure of 2, which was determined by means of single crystal X-ray diffraction (orthorhombic space group Pbcm; lattice dimensions at 200 K: a = 18.7122(8), b = 20.9653(9), c = 57.340(3) Angstrom, V = 22494.9(17) Angstrom(3): R-1 [I > 2sigma(1)] = 0.0674; wR(2) = 0.1271) differs from 1 in that the [Co-4(mu(4)-Se)(SnSe)(4)](10-) anions are embedded in an even more complex counterion aggregation; the latter contains solvated K+ cations, additional [SnSe4](4-) groups and, in contrast to 1, Cl- anions. As a part of the counterion assembly, the Cl- and some of the K+ ions are arranged in a previously unknown [(mu(6)-Cl)(2)K-9](7+) coordination aggregate, formed by two face-sharing [(mu(6)-Cl)K-6] octahedra.
