Molecular Complex of Cadmium(II) Trifluoroacetate with Triphenylphosphine: Crystal Structure and Luminescence Properties

Аннотация

Cadmium compound [Cd(CF₃COO)₂(Ph₃P)₂] is synthesized, and its crystal structure is determined. The crystals are monoclinic: space group C2/c, a = 20.318(4), b = 10.432(2), c = 18.661(4) Å, β = 104.18(1)°, V = 3834.8(13) ų, Z = 4, ρ_calcd = 1.495 g/cm³. The Cd atom arranged on the 2-fold crystallographic axis has a distorted octahedral coordination due to four oxygen atoms of crystallographically equivalent trifluoroacetate ligands and two phosphorus atoms of triphenylphosphine. Each fluorine atom of the trifluoroacetate groups is randomly disordered over three equally probable positions. The compound is luminescent.
