The Preparation,Characterization and X-ray Structural Analysis of Tetrakis[1,3-dimethyl-2(3H)-imidazoleselone]cadmium(II) Hexafluorophosphate

Abstract A new compound, Cd(dmise)₄]PF₆]₂, has been synthesized and characterized via standard solid and solution state methods including single crystal X-ray crystallography (dmise = 1,3-dimethyl-2(3H)-imidazoleselone). The title compounds crystallizes in orthorhombic space group P bcn with a = 12.783(3), b = 22.206(4), c = 13.153(3) ?, V = 3733.8(13) ?³, Z = 4. The complex is a high melting, yellow water soluble 2:1 electrolyte solid that state has a flattened tetrahedral CdSe₄ coordination geometry. To date this is the only structural study reported for a homoleptic selenourea complex of cadmium. Graphical abstract The Preparation, characterization and X-ray structural analysis of Tetrakis1,3-dimethyl-2(3H)-imidazoleselone]cadmium(II) hexafluorophosphate Daniel J. Williams, Bradley J. McKinney, Ben Baker, Kevin P. Gwaltney and Donald VanDerveer Tetrakis1,3-dimethyl-2(3H)-imidazoleselone]PF₆]₂ is prepared in 82% yield by direct combination of cadmium acetate dihydrate, ammonium hexafluorophosphate, and the ligand in boiling acetonitrile. X-ray crystallography shows a structure with a distorted tetrahedral coordination sphere around the cadmium. This is the first report of a structural characterization of a homoleptic cadmium selenourea complex.
