Application to a square planar, trigonal bipyramidal ...
Synthesis, crystal structure and properties of trigonal bipyramidal [M(L5)2(H2O)]·H2O complexes [M = cobalt(II) (S = 3/2) or copper(II) (S = 1/2); HL5 = N-(2-chloro-6-methylphenyl)pyridine-2-carboxamide] Using a bidentate ligand N-(2-chloro-6-methylphenyl)pyridine-2-carboxamid...
We conclude that the resulting intense colors of pigments are due to the crystal field splitting associated with the TBP coordination and the short apical M 鈥揙 bonds ( M = Mn, Fe, Cu). Other colored compounds containing TBP coordination are briefly reviewed. Blue and/or bluish-purple ...
The data were fitted with two different methods which either took into account or neglected the zero-field splitting of single ions. The coupling was found to be antiferromagnetic with J = 9.8(2) cm -1 (J is defined through the hamiltonian h = JS 1路S 2). The extent of the magnetic ...

On the basis of absorption, luminescence and, in part, magnetic circular dichroism spectroscopic measurements, the crystal field (CF) splitting pattern of 1 and also of (CH 3 OCH 2 CH 2 C 5 H 4 ) 3 Pr ( 2 ) could be derived. The parameters of an empirical Hamiltonian were fitted to...

Each cobalt(II) ion in 1 is five-coordinate by a monodentate azide ligand and a tetradentate monodeprotonated H2tba-group building a slightly distorted trigonal bipyramidal surrounding. Compound 2 is also a mononuclear species whose structure was previously reported and only some of its structural ...
