K2Li(NH2)(3) (1) was the only crystalline product obtained from the reaction of potassium with dilithium decahydro-closo-decaborate Li2B10H10 in liquid ammonia at -38 degrees C. The compound crystallizes in the space group P4(2)/m with Z=4, a = 6.8720(5) angstrom, c=11.706(1)angstrom and V=552.81(7)angstrom(3). The investigated crystal-chemically isotypic sodium compound K2Na(NH2)(3) (2) was merohedrally twinned and crystallized from a reaction mixture containing potassium and disodium decahydro-closo-decaborate Na2B10H10 in liquid ammonia with a = 7.0044(5) angstrom, c = 12.362(1) angstrom and V= 606.48(9) angstrom(3). The compounds contain pairs of edge sharing tetraamidolithium or tetraamidosodium tetrahedra which are interconnected by potassium ions forming three-dimensional infinite networks.
