Abstract

The alkoxides M(ORX)n wherein M is an alkaline-earth or rare-earth and ORX is a fluoroalkoxo or bromoalkoxo group exhibit the properties to form pure fluoride materials by hydrolysis at room temperature. Using this property, we synthesized pure barium and europium fluoride and pure alkaline-earth bromide. The hydrolysis of an heteroleptic species, Ba(OCH2CH2Br)[OCH(CF3)2] allowed pure and crystalline BaFBr materials to be obtained at room temperature.
