A new, general strategy for achieving planar tetracoordinate geometries for carbon and other second row periodic elements
Abstract
Highly stable structures with planar tetracoordinate central atoms, Al4O, Al4N–, Al3SiN, cis-Al2Si2C, trans-Al2Si2C and AlSi3B, are predicted computationally at the ab initio MP4SDTQ/6-311 + G*//MP2(full)/6-31G* level.
