Abstract The method of mass spectrometry with laser desorption-ionization was used to study the composition of tantalum oxochloride anion-radicals clusters in the gas phase, formed as a result of hydrolysis of the reaction products of NbCl5 with acetylene - an organometallic nanosized composite TaCl3,7C15H22. The families of tantalum anions containing from 1 to 13 tantalum atoms was determined. The highest in relative concentration members of these families can be distinguished into homologous series of anion-radicals (A-G), the composition of which can be described by the formulas: A - [TanO2nCln+1]- (n = 1–10); B - [TanO2n-1Cln+3]- (n = 1–10); C - [TanO2n-2Cln+5]- (n = 1–7); D - [TanO2n-3Cln+7]- (n = 2–4); E − [TanO2n+1Cln-1]- (n = 3–12); F - [TanO2n+2Cln-3]- (n = 5–10); G - [TanO2n+3Cln-5]- (n = 6–10).

氧氯化钽阴离子簇的激光解吸-电离质谱

摘要 采用激光解吸-电离质谱法研究了气相中氧氯化钽阴离子自由基团簇的组成，该团簇是由 NbCl5 与乙炔的反应产物水解形成的 - 一种有机金属纳米复合材料 TaCl3， 7C15H22。测定了含有 1 到 13 个钽原子的钽阴离子族。这些家族中相对浓度最高的成员可以分为同源系列的阴离子自由基（AG），其组成可以用公式描述：A - [TanO2nCln+1]-（n = 1-10）；B - [TanO2n-1Cln+3]- (n = 1–10); C - [TanO2n-2Cln+5]- (n = 1–7); D - [TanO2n-3Cln+7]- (n = 2–4); E - [TanO2n+1Cln-1]- (n = 3–12); F - [TanO2n+2Cln-3]- (n = 5–10); G - [TanO2n+3Cln-5]- (n = 6–10)。
