摘要：

{K-[2 2 2]-Crypt}2Se7.H2O has been prepared by the reaction of a solution of potassium polyselenide in dimethylformamide at room temperature as black crystals, which were characterized by IR spectroscopy as well as by an X-ray structure determination. Space group P2(1/n), Z = 4, 5055 observed unique reflexions, R = 0.103. Lattice dimensions at 20-degrees-C: a = 1435(1), b = 1320(1), c = 2966(2) pm, beta = 102.50(6)-degrees. The heptaselenide ion represents approximately part of a helical chain of polymeric selenium.
