碱式氯化钴是一种无机化合物，化学式为Co2(OH)3Cl。它有α型和β型两种结构，且都为层状结构。[3]它的氘代化合物Co2(OD)3Cl是已知的。[4]
制备及性质
碱式氯化钴可由0.2 mol/L的氯化钴和0.2 mol/L的氢氧化钠在pH 5.5的溶液中反应得到，[5]或通过二氯化二硫脲合钴的乙醇溶液和0.1 mol/L氨水在100 °C下水解制得。[1]
它在空气中于280 °C分解，生成Co(OH)Cl和Co3O4，其中Co(OH)Cl在440 °C继续分解：[6]
- 6 Co2(OH)3Cl + O2 → 6 Co(OH)Cl + 2 Co3O4 + 6 H2O
- 12 Co(OH)Cl + O2 → 2 Co3O4 + 6 CoCl2 + 6 H2O
而在氮气中，差热分析在409和465 °C归属于下列两种反应：[6]
- Co2(OH)3Cl → Co(OH)Cl + CoO + H2O
- 2 Co(OH)Cl → CoO + CoCl2 + H2O
相关化合物
氯化钴和氢氧化钠溶液（或氨水[7]）反应，除了会生成Co2(OH)3Cl外，还会生成Co(OH)Cl [CAS 61219-65-6]和Co5(OH)9Cl [CAS 60936-08-5]。[8]
