synthetic disilikat.

A compound consisting of silicon-silicon bond is stable between the two atoms a negative charge - five-coordinate silicon atoms - silicates - have been synthesized and isolated for the first time by Japanese researchers. Species - species disilikat new memberipak unimaginable insights into the silicon chemistry and materials useful for making new optical and conductive.

Usually combined with four silicon atoms - the other atoms to form four-coordinate structure, which can form a bond with the silicon atom coordinates four others. Like structures form the basis of crystalline silicon used for semi-conductors and organosilicon compounds. Previously, the largest number of coordination atoms - atoms of silicon to allow for bonding of silicon-silicon is widely considered to be stable there were four.

Now, Naokazu Kano and his colleagues at Tokyo University and Institute for Molecular Science in Japan have created a Si-Si bond directly between the atoms - five-coordinate silicon atoms from silicates. Surprising result because a bond would be expected to split because Steric and electrostatic repulsi strong between atoms - atoms of silicon. This team successfully synthesized and dianionic compounds mengkarakteristikan which includes atoms - five-coordinate silicon atoms, with Si-Si bond. This is the first example of a silicon-silicon bond.

electrostatic repulsi why do not cause damage to molecules - molecules is that the charge - a negative charge is formally only on silicon. Charge - the charge that [is] distributed among the atoms - atoms that many of the surrounding atoms - atoms of silicon, leaving the [silicon] is positively charged, without Coulomb repulsi.

However, Kost still confused on disilikat dianionic stability. None hydrolysis or heating that cause decomposition compounds, although compounds of silicon mono-nuclear hypervalent tend to dekompos quickly when exposed to air and moisture.

If we can accumulate these bonds in the series to make the silicon wire is made of silicates moieties, [molecular orbital remains high on the molecular orbital not stay low] the energy gap will be more down to help in creating a conductive material such as injecting new polyacetylene.
