Single crystals of a new compound, ammonium tetrabromocuprate (II) dihydrate were obtained by slow evaporation method. The crystals were characterized through thermogravimetric (TG), differential thermal analysis (DTA), low temperature differential scanning calorimetric (DSC) methods and infrared (IR) spectroscopic technique. While the TG study confirms the stoichiometry of the compound, the thermal hystereses in DSC indicate the occurrence of first order phase transitions in the compound at low temperatures. The FTIR spectrum of the compound characterizes the various chemical bond vibration frequencies. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
