摘要：

The title compound was prepared by the reaction of excess selenium with strontium diselenide in DMF in the presence of 15-crown-5. [Sr(15-crown-5)2]Se, forms black crystals, which are soluble in DME They were characterized by FIR spectroscopy and by an X-ray structure determination. Space group P2(1)/n, Z = 4, 2381 observed unique reflections, R = 0.073. Lattice dimensions at 1-degrees-C: a = 1 228.7, b = 1 893.4, c = 1 575.7 pm, beta = 99.15-degrees. The compound consists of [Sr(15-crown-5)2]2+ ions in which the strontium ion is coordinated by the oxygen atoms of the crown ether molecules in a sandwich-like fashion, and of Se9(2-) ions with a chain structure, which has a topolocical resemblance with the bicyclic ion Se10(2-).
