Mar 1, 2016 · If you increase the overall size of the tetrahedron however by exchanging oxide by sulfide you will end up in the silicon (IV)sulfide structure which is essentially long chains of …

Jul 18, 2019 · Remember that a tetrahedron is symmetric, so that it looks the same when viewed from any of its four corners. So if the tetrahedral methane molecule had a non-zero dipole …

Feb 7, 2022 · Yes, since each tetrahedron is $\ce {SiO3^ {2-}}$ when we properly count oxygen atoms, two $\ce {Li^+}$ ions will attach to each tetrahedron to neutralize it, which matches the …

Silicon exists in a structure similar to diamond, with 4 silicon atoms bonded to each other in a tetrahedron. Why do we not see it exist in a structure like graphite?

How can one predict whether a given complex ion will be square planar or tetrahedral when its coordination number is 4 using crystal field theory? Is it possible to theoretically predict this?

Sep 10, 2021 · nBuLi and tBuLi can take part in halogen metal exchange OR deprotonate. Is there any way to predict which it favours?
