Synthesis and Structural Characterization of New Polyether Complexes of Germanium(II) and Tin(II)

A series of germanium(II) and tin(II) bromide polyether complexes have been synthesized. Specifically, [GeBr([15]crown-5)][GeBr 3 ], [GeBr([18]crown-6)][GeBr 3 ], [GeBr(triglyme)][GeBr 3 ], [GeBr(tetraglyme)][GeBr 3 ], [SnBr([18]crown-6)][SnBr 3 ], [Sn([15]crown-5)2][SnBr 3 ] 2 , [SnBr(triglyme)][SnBr 3 ] and [SnBr(tetraglyme)][SnBr 3 ] have been fully characterized including by single crystal X-ray diffraction. The synthesis of [GeBr(dibenzo[24]crown-8)][GeBr 3 ] and [GeCl(dibenzo[24]crown-8)][GeCl 3 ] are also reported, along with the crystal structure of the latter’s water adduct, which features a water molecule adjacent to the GeCl+ ion within the cavity of the crown ether.
