By X-ray crystallographic analysis, the molecular structure of 3,4,7,8-tetragermacycloocta-1,5-diyne 1b has been established to be planar and quite similar to that of silicon analog 3,4,7,8-tetrasilacycloocta-1,5-diyne 1a. The detailed comparison of

The ionization potentials of gaseous and solid oligogermanes and polygermanes were measured in the 5.31–8.60 eV regions, and were assigned to ionizations from the germanium framework, by ultraviolet photoelectron spectroscopy. The values of ionizat

Diphenylselenogermanes are prepared for the first time in 32–89% yield by the reaction between sodium benzeneselenolate and dihalogermanes (halogen=Cl or Br). The X-ray structure of 1,1-diphenylseleno-1-germacyclopentane has been determined.

The steric compression effect (γ-effect) of γ-carbon on 77Se chemical shift in mono- and diselenogermanes has been first evaluated by 77Se NMR spectroscopy. The γ-gauche effect falls in the range between −59.1 and −13.6 ppm (upfield shift).

Molecular mechanics calculations in germacyclohexane and methyl-substituted germacyclohexanes reveals that (i) the ring is flattened around the germanium and that (ii) a methyl group on germanium has a slight preference for the axial conformation rat

An X-ray crystallographic analysis and dynamic 1H n.m.r. study have shown that the title compound exists in a symmetrical 2,5-twist-boat conformation both in the solid state and in solution; an unusually high barrier for interconversion between the t
