Molecular structure of4. Hydrogen atoms are omitted except for NH entities. Thermal ellipsoids are presented at the 50% level of probability. Selected bond lengths (in ) and bond angles (in ): Fe1N3, 1.999(3), Fe1N4 1.938(3), Fe1Cl1 2.3563(9), N3Fe1N4 84.04(11). The asymmetric unit contains two independent molecules, resulting in four iron centers exhibiting very similar environments. A full table (Table S1) of the metric parameters is given in theSupporting Information.
