摘要
本文描述了两个具有相似阴离子骨架的化合物,犤Na2(H2O)10(NH4)4犦犤V10O28犦(1)和犤Na2(H2O)10(NH4)4犦犤V9MoO28犦(2)。化合物1的阴离子是一个常见的钒十骨架,而化合物2与化合物1是同晶异质体,化合物2的阴离子是混有一个钼原子的钒十骨架。X-射线晶体结构测定表明,这两个化合物均属于三斜晶系,P1珔空间群。晶胞参数分别为化合物1:a=0.86024(4)nm,b=1.04561(5)nm,c=1.12828(4)nm,α=68.833(1)°,β=87.158(1)°,γ=67.065(1)°;化合物2:a=0.86511(3)nm,b=1.04549(5)nm,c=1.12446(5)nm,α=69.071(1)°,β=87.145(1)°,γ=66.982(1)°。
Two compounds with similar anion backbone, [Na2(H2O)10(NH4)4] (1) and [Na2(H2O)10(NH4)4] (2), are discribed. The anion of 1 is of decavanadate with normal structure, while the anion of 2 has a molybdenum atom mixing with four vanadinum atoms at certain positions in the similar backbone of the decanucleus structure.
