Kr. Adam et al., LOCAL-DENSITY FUNCTIONAL THEORY ANALYSIS OF THE STRUCTURES AND ENERGIES OF THE ISOMERS OF LOW-SPIN [NI(CYCLAM)](2+), Inorganic chemistry, 36(3), 1997, pp. 480
Density functional theory calculations using the SVWN5 functional and
the 6-311G basis sets have been found to successfully model the geome
tries of the trans-I to trans-V configurational isomers of low-spin [N
i-(cyclam)](2+). The relative energies of the (gas-phase) isomers is s
imilar to that determined by simple molecular mechanics investigations
