Abstract
The addition reaction of two pyridine molecules to Ni(II) β-diketonate bis-chelate was studied by quantum chemical density functional theory calculations (B3LYP/6-311++G(d, p)). The addition of the first pyridine molecule to the trans-position was found to be the most favorable channel for this two-stage process; the reaction is accompanied by a change in the spin state of the system. The transition between the potential energy surfaces of different multiplicity occurs at the first stage without considerable energy expenditure; the addition of the second pyridine molecule is barrierless.
