From: Octa-coordinated alkaline earth metal–dinitrogen complexes M(N2)8 (M=Ca, Sr, Ba)
Calculated geometries and bond lengths. Calculated equilibrium structures and interatomic distances [Å] of M(N2)8 and [M(N2)8]+ (M = Ca, Sr, Ba) at the M06-2X-D3/def2-TZVPP level. Bond dissociation energies D0 [kcal mol−1] for loss of one N2 and (in parentheses) loss of eight N2
