锗酸盐

在化学中，锗酸盐（英語：germanate）是含有锗的含氧阴离子的化合物。在无机化合物的命名中，锗酸作后缀时，则代表中心为锗原子的多原子阴离子，^[1]例如六氟锗酸钾，K₂GeF₆。^[2]

锗类似于硅，它可以形成许多含有{GeO₄}^[2]四面体单位的化合物，但它也可以有5^[3]和6^[2]的配位数。所有主要硅酸盐和铝硅酸盐（英语：Aluminosilicate）的类似物都已被制备。^[4]比如，Mg₂GeO₄（晶状如橄榄石和尖晶石）、CaGeO₃（钙钛矿结构）和Be₂GeO₄（硅铍石（英语：phenakite）结构）都与对应的硅酸盐有所类似。^[4]^[5] BaGe₄O₉结构复杂，含有配位数位4和6的锗原子。^[5]锗酸盐在地球科学十分重要，因为它们的结构与硅酸盐相似，在研究地幔中的硅酸盐矿物的行为时可用作类似物。^[6]例如，MnGeO₃有辉石型结构，与MgSiO₃相似，而这个硅酸盐是重要的地幔矿物。^[7]^[8]^[9]

碱金属的原锗酸盐，M₄GeO₄，都单独含有GeO4−
4离子。它们会形成含有GeO(OH)−
3、GeO
2(OH)2−
2和[(Ge(OH)₄)₈(OH)₃]³⁻的酸性溶液。^[2]二氧化锗的中性溶液含有Ge(OH)₄，但在pH高的环境下，诸如GeO(OH)−
3和GeO
2(OH)2−
2的锗酸根离子会出现。^[10]
