Nitrogen versus carbon in planar pentacoordinate environments supported by Be₅H _n rings.

ABSTRACT: NBe₅H _n ^n-3 (n = 0-5) (0A-5A) species with a novel planar pentacoordinate nitrogen (ppN) were designed by the isoelectronic substitution of the C atom in planar pentacoordinate carbon (ppC) species CBe₅H _n ^n-4 (n = 0-5) with an N atom. The highly flexible H atoms found in ppC species CBe₅H₂ ^2- and CBe₅H₃ ^- were fixed upon the nitrogen substitution, as mirrored by the non-flexible H atoms in their ppN analogues NBe₅H₂ ^- (2A) and NBe₅H₃ (3A). Moreover, the N atom was found to fit the H-surrounded Be₅ rings better than the C atom because the ppC species CBe
