Tetranuclear homoleptic copper and silver aryls: 2,4,6-Triethylphenylcopper and 2,4,6-triethylphenylsilver
摘要:
The ethyl analogues of mesityleopper and mesitylsilver, 2,4,6-triethylphenylcopper and 2,4,6-triethylphenylsilver, have been prepared and characterised by means of crystal structure determination. Three different compounds, [Cu-4(Et3Ph)(4)] center dot 2C(6)H(5)CH(3) (1), [Cu-4(Et3Ph)(4)]center dot 1/2(C2H5)(2)O (2) and [Ag-4(Et3Ph)(4)] center dot 1/2C(6)H(5)CH(3) (3), have thus been obtained by crystallisation from toluene or diethylether/tetrahydrofuran. All three show the square-planar metal core, most characteristic of homoleptic copper and silver aryls. The ordered (1) or disordered (2 and 3) solvent molecules are situated in the channels formed between the organometallic complexes, there being no strong directional interactions between the solvent and 2,4,6-triethylphenyleopper or 2,4,6-triethylphenylsilver.
