Figure 1
A view of the title mononuclear complex, (I), with the atomic numbering scheme. Displacement ellipsoids are drawn at the 50% probability level. Unlabeled atoms are related by an inversion center to the labeled atoms. H-atom positions H32, H33, H42 and H43 are all half-occupied. Thus, half of the time, hydrogen bonding occurs between atoms H32 and O4 (pictured), while the other half of the time, hydrogen bonding occurs between atoms H43 and O3 (not pictured). |
