This would make this particular pyrrole group unequivalent with the others. |

There are also other related unequivalent tilings, such as the hexagon-boat-star and Mikulla Roth tilings. |
|
By contrast, the three ligands in the meridional isomer were chemically unequivalent, so the DFT-calculated peak of each carbon atom showed splittings. |
|
In fact, they allow a more sterically and electronic defined architecture around the metal centre, because the phosphorus center can be easily modified by introducing unequivalent substituants. |
|
Unequivalent carbon atoms in a compound can be distinguish by 13C NMR spectrum, as different electron densities arise from varied chemical environments. |
