摘要

By solvothermal reaction of ortho-vanadicacid ester (1)(infinity)[VO(OMe)(3)] with squaric acid and potassium or caesium hydroxide the compounds K-4[V-IV O-12(12)(OCH3)(16)(C4O4)(6)] (2) and Cs-10[V-IV O-24(24)(OCH3)(32)(C4O4)(12)][V-IV O-8(8)(OCH3)(16)(C2O4)] (3) could be syntesized. With tetra-n-butyl- or tetra-n-ethylammonium fluoride [N(nBu)(4)](2)[V-IV O-8(8)(OCH3)(16)((VOF4)-O-IV)] (4) and [N(Et)(4)](2)-[V-IV O-8(8)(OCH3)(16)(V-IV OF4)] (5) could be isolated. In 2 and 3 the corners of a tetrahedron or cube resp. are occupied by {(VO)3(OMe)4} groups and connected along the edges of the tetrahedron resp. cube by six or twelve resp. squarato-groups. The octanuclear anions in the compounds 3, 4, and 5 are assumedly built up by fragments of the ortho-vanadicacid ester (1)(infinity)[VO(OMe)(3)], Around the anions C2O42- or VOF4- these oligormeric chains are closed to a ring.
