New crystalline compounds of the general composition Co(NH3)6[PuO2L]2A · nH2O, where L = CH2(COO)2 and A = HCOO, CH3COO, C2H5COO, and HL, were prepared by adding a small excess of Co(NH3) 6 3+ ions to freshly prepared neutral Pu(V) malonate solutions containing single-charged organic anions. The complexes are sparingly soluble in water and fairly stable when stored in air; they have a similar structure. Previously unknown double Np(V) malonates Co(NH3)6[NpO2L]2A · nH2O, where A = HCOO, CH3COO, and C2H5COO, isostructural with the corresponding Pu(V) compounds, were also prepared. The IR spectra of the new compounds were measured, and their behavior at heating was examined.
通过向新制备的含有单电荷有机阴离子的中性钚(V)丙二酸盐溶液中加入少量过量的 Co(NH3) 6 3+ 离子,制备出了一般组成为 Co(NH3)6[PuO2L]2A - nH2O(其中 L = CH2(COO)2,A = HCOO、CH3COO、C2H5COO 和 HL)的新型结晶化合物。这些复合物很少溶于水,在空气中储存时相当稳定;它们具有相似的结构。此外,还制备出了之前未知的双 Np(V)丙二酸盐 Co(NH3)6[NpO2L]2A - nH2O(其中 A = HCOO、CH3COO 和 C2H5COO),它们与相应的 Pu(V)化合物结构相同。测量了新化合物的红外光谱,并考察了它们在加热时的行为。
