Table 2.

Relative energies computed for the cis and trans isomers of [FurNeu](Cu2(μ-O))(OTf)2, 5 (singlet and triplet states), at either the BP86/def2-TZVP or at the B3LYP/def2-TZVP levels (see also the Theory section in SI for details). All values are given in kcal/mol.

model B3LYP/def2-TZVP BP86/def-TZVP
trans (singlet) 0.0 +5.1
trans (triplet) +1.0 +4.3
cis (singlet) +6.9 +1.8
cis (triplet) +5.2 0.0
