摘要：
A [K(18-crown-6)] salt of the (Ph(2)PSe)(2)NH ligand was obtained by reaction of [K(Ph(2)PSe)(2)N] with 18-crown-6 [monoclinic space group C2/c with the cell parameters a = 20.310(2), b = 8.894(2), c = 22.978(3) Angstrom, beta = 114.66(2)degrees, and Z = 4]. The potassium ion has the rare coordination number 10, It is coordinated to the six oxygen atoms of the crown ether and to four carbon atoms, two from each of the two anionic Ligands neighboring the cationic moiety.
