摘要：
Complexes of Sr with the polyether 18-crown-6 (18C6) and ClO4-, BF4-, and BPh4- anions are synthesized and studied. The IR spectra and x-ray powder patterns are recorded and thermogravimetric analysis is performed for the prepared compounds. In contrast with complexes with BF4- and BPh4-, the compound with ClO4- decomposes with evolution of large amounts of heat. The reaction is exothermic as opposed to the decompositions of the BF4- and BPh4- complexes. The solubility of the complexes in THF is determined. It varies in the range from 0.9.10(-4) to 5.10(-4) M. The complex [Sr(18C6)](BPh4)2 is also slightly soluble in water and ethanol (solubility of the order of 10(-2)-10(-3) M). This may have practical application.
