The Preparation, Characterization and X-ray Structural Analysis of Tetrakis [1-Methyl-3-(2-Propyl)-2(3 H )-Imidazolethione]Cadmium(II) Hexafluorophosphate

A new compound, [Cd( mipit ) 4 ][PF 6 ] 2 has been synthesized and characterized via standard solid and solution state methods including single crystal X-ray crystallography ( mipit = 1-methyl-3-(2-propyl)-2(3H)-imidazolethione). The title compound crystallizes in tetragonal space group I4 1 /a with a = 12.478(2) Å, b = 12.478(2) Å, c = 28.806(6) Å, and Z = 4. The complex is a high melting, colorless solid that has a distorted tetrahedral CdS 4 coordination geometry. Thermogravimetric analysis results for the title compound as well as for another potential CdS synthon and two potential CdSe synthons are reported. Graphical Abstract The synthesis and characterization of the title compound, a new ionic homoleptic cadmium complex, tetrakis[1-methyl-3-(2-propyl)-2(3H)-imidazolethione]cadmium(II) hexafluorophosphate is reported. The results of a single crystal X-ray diffraction analysis reveal a distorted tetrahedral CdS 4 coordination sphere about the cadmium.
