We present experimental data on the synthesis and investigation of the superconducting and structural properties of organometallic fullerides M_(3−n)(NR₄)_(n)C₆₀, where M = K, Rb; R = hydrogen H, deuterium D, methyl Me, ethyl Et, butyl Bu; n = 1, 2, 3, synthesized by exchange reactions of homofullerides of alkali metals of composition K₃C₆₀ and Rb₃C₆₀ with ammonium halides in the medium of absolute toluene or tetrahydrofuran (THF) at temperatures from 23°C to 110°C. We have studied also superconductivity in Rb₂NH₄C₆₀ and Rb₂ND₄C₆₀ samples with replacement of hydrogen for deuterium in ammonium, as well as in K₂NH₄C₆₀ and K₂ND₄C₆₀. The superconducting transition temperature did not change with replacement H by D within the measurement accuracy.

有机金属富勒分子M（3-n）（NR4）（n）C60的合成和超导，其中M = K，Rb；R = H，D，Me，Et，Bu; n = 1、2、3

我们提供有机金属富勒分子M _{（3- n）}（NR ₄）_（n） C ₆₀的合成和超导和结构性质研究的实验数据，其中M = K，Rb; R =氢H，氘D，甲基Me，乙基Et，丁基Bu; n  = 1、2、3，是通过在绝对甲苯或四氢呋喃（THF）介质中于23°C至110°C的温度下，将组成为K ₃ C ₆₀和Rb ₃ C ₆₀的碱金属高富勒酸与卤化铵交换反应合成的℃。我们还研究了Rb ₂ NH _4中的超导性C ₆₀和Rb ₂ ND ₄ C ₆₀样品，用氢气替代铵中以及K ₂ NH ₄ C ₆₀和K ₂ ND ₄ C _60中的氘。在测量精度范围内，用D代替H不会改变超导转变温度。
