✦ Synopsis

For a proof whether the chelate angle is the root cause of a triplet level being the ground state of Kuchen's planar Ni(II) compounds, Bridgeman and Gerloch must use model parameter values which are derived from experiment. Their preliminary calculations employ parameters that are in conflict with their own cellular ligand-field (CLF) computations when using a parameter fit which they call 'well defined'. The use of the void-extended CLF scheme for solving the present problem is questioned, particularly when parameter comparability to other compounds is abandoned -as this model implies.

The origin of the triplet ground state in the recently synthesized paramagnetic, planar-coordinated complexes of nickel(II), Ni[t-bu2P(O)NR]2; R = i-propyl, c-hexyl, is ascribed to the small chelate bite angle in these molecules. The nature of the singlet-triplet crossover in planar d 8 complexes is
