The salt metathesis reaction of Na(pmtz)·HO [pmtz 5-(pyrimidyl)tetrazolate] and PuBr·HO in an aqueous media leads to the formation of the mononuclear compound [Pu(pmtz)(HO)]·(3 + ) HO (, = ∼8) that is isotypic with the lanthanide compounds [Ln(pmtz)(HO)]·(3 + ) HO (Ln = Ce-Nd). Dissolution and recrystallization of in water yields the dinuclear compound {Pu(pmtz)(HO)}(pmtz)·14HO (), which is isotypic with the lanthanide compounds {Ln(pmtz)(HO)}(pmtz)·14HO (Ln = Nd and Sm). Like their nine-coordinate ionic radii, the M-O and M-N bond lengths in / and /, respectively, are within error of one another. The Laporte-forbidden 4f → 4f and 5f → 5f transitions are also assigned in the UV-vis-NIR spectra for these -element tetrazolate coordination compounds.
在水介质中，Na(pmtz)·HO [pmtz为5-(嘧啶基)四唑盐] 与PuBr·HO发生复分解反应，生成单核化合物[Pu(pmtz)(HO)]·(3 + ) HO (， = ∼8)，它与镧系化合物[Ln(pmtz)(HO)]·(3 + ) HO (Ln = Ce - Nd) 同型。 在水中溶解并重结晶得到双核化合物{[Pu(pmtz)(HO)](μ - pmtz)}(pmtz)·14HO ()，它与镧系化合物{[Ln(pmtz)(HO)](μ - pmtz)}(pmtz)·14HO (Ln = Nd和Sm) 同型。 与它们的九配位离子半径一样，/和/中M - O和M - N键长分别在彼此的误差范围内。 在这些 - 元素四唑盐配位化合物的紫外 - 可见 - 近红外光谱中也归属了拉波特禁阻的4f→4f和5f→5f跃迁。
