“…60 For the bis-pyrazole complex, the crystal structure has not been published but is said to have the two pyrazole ligands not in parallel planes, but rather at dihedral angles of 45°and 54°f or the two independent molecules, with the average ligand plane orientation of the two ligands lying very close to the porphyrin nitrogens of two opposite pyrrole rings for the two independent molecules in the unit cell. 61 The ESEEM data are sensitive to the extent of only about (20°to ligand orientation, 37 so it is not possible to determine whether the ligands have their crystallographically observed orientations in frozen solution, or adopt parallel ligand orientations, but in either case, our experimental results are consistent with γ ) 0°and hence γ 0 ) 0°, at least for the aVerage ligand plane orientation.…”

Co- and Counterrotation of Magnetic Axes and Axial Ligands in Low-Spin Ferriheme Systems

The orientation of the principal axes of the g tensor with respect to the relationship of axial ligand planes to the porphyrin nitrogens has been studied in the framework of the one-electron crystal field model for tetragonal and rhombic low-spin d5 complexes such as ferriheme centers. All five d atomic orbitals were taken into account for two different ground-state electronic configurations, the “normal” (d xy )2(d xz ,d yz )3 and the “novel” (d xz ,d yz )4(d xy )1 configurations. The expressions for the g tensor, g values, and magnetic axes were derived on the basis of first-order perturbation theory. The conditions for co- and counterrotation of magnetic axes with rotation of planar axial ligands away from the porphyrin nitrogens toward the meso positions and beyond, as well as the order of g values, have been analyzed. It is found that counterrotation is the only possibility for the (d xz ,d yz )4(d xy )1 configuration and that it is also by far more common for the (d xy )2(d xz ,d yz )3 electron configuration. The possibilities of nonlinear co-/counterrotation are also explored. The predictions of this treatment are then compared to experimental results obtained from single-crystal EPR, glassy sample ESEEM, and solution NMR spectroscopic studies. It is clear that the majority of experimental systems reported thus far follow the major predictions of this treatment: Most systems exhibit angle-for-angle (linear) counterrotation of the g or χ tensor with rotation of planar axial ligands away for the N−Fe−N axes. Hence, knowing the structure of a model heme or heme protein, and in particular, the orientation of (fixed) axial ligand planes, one should be able to predict the approximate orientation of the in-plane magnetic axes. This knowledge provides a check on the values obtained in new solution NMR, single-crystal EPR or frozen solution ESEEM experiments.

“…52 52 This proposal to include housing was approved in working group meetings leading up to the initial funding and launch activities for the study, but has not been implemented to date. The study directors are apparently still open to proposals to improve the survey instrument, however (Scheidt, 2006). effects poses significant methodological as well as data challenges.…”
