Figure 3
A histogram of observed T–T distances and T⋯T separations in all chain-silicate minerals and selected synthetic compounds. The areas in pink from 2.616 to 2.910 Å represent the range in which T–T distances are not allowed during embedding. The area in pink from 3.210 to 3.713 Å is the range in which T–T distances and T⋯T separations are not allowed during embedding. |
