• Popis: The reaction of Cu(PPh3)2NO3 with K[Ph2P(Se)-N-P(Se)Ph2] produced a tricoordinate copper(I) complex, Cu(PPh3)[Ph2P(Se)-N-P(Se)Ph2], containing the novel inorganic (carbon-free) CuSe2P2N metallocycle. The same diselenium reagent gave with Co(PPh3)2Cl2 a spirobicyclic compound Co[Ph2P(Se)-N-P(Se)Ph2]2, containing the novel inorganic CoSe2P2N metallocycle. The crystal structure of the two compounds was investigated by X-Ray diffraction. In both compounds the inorganic metallocycles are nonplanar and display strongly distorted twisted boat conformations.
