Polymerizations in single crystals have rarely been described—in the case of the title compound they are even reversible. The rebuttoning of the bonds can be regarded as bond stretching isomerism, which is currently the subject of controversial discussion in many areas of chemistry. The geometrical arrangement of the monomeric Ge 4 6− ions in the crystal is shown in the picture.
