1,3-Digermabicyclo[1.1.0]butane with an Inverted Bridge Ge-Ge σ Bond
1,3-Digermabicyclo[1.1.0]butane <B>2</B> was synthesized as yellow crystals. The molecular structure, <SUP>13</SUP>C NMR and UV–vis spectra, and theoretical calculations have revealed that <B>2</B> is a typical long bond isomer, similarly to the silicon congener <B>1</B>. Structural comparison between <B>1</B> and <B>2</B> is achieved.
