摘　　要：合成了四氯合金属（Ⅱ）酸正十烷铵（Ｃ１０Ｈ２１ＮＨ３）２ＭＣｌ４（Ｃ１０Ｍ，Ｍ＝Ｃｕ，Ｚｎ，Ｃｄ，Ｈｇ，Ｍｎ，Ｃｏ，Ｎｉ），对它们进行了ＩＲ和ＤＳＣ分析．Ｃ１０Ｍｎ，Ｃ１０Ｃｏ，Ｃ１０Ｚｎ和Ｃ１０Ｃｕ的固－固转变温度在３２℃～８０℃之间，固－固转变为５５～８３Ｊ／ｇ．可逆性好，化学性质稳定，是一类有希望的固－固相变材料．A series of bis (n--decylammonium) tetrachlorometallates (Ⅱ) (n--C10H21NH3)2MCl4 (C10M, M = Cu, Zn, Cd, Hg, Mn, Co, Ni ) were synthesized and elementary analysis was Carried out. Their solid-solid phase transitions were studied using DSC and IR. Transition temperature of the C10M compounds between 32-80℃,solid--solid phase transition enthalpy of C10Mn, C10Co, C10Zn and C10Cu between 55～83(J/g), their are potential thermal energy storage materials.
