Figure 2.

Perspective view of the LT P1 (83 K), INT Pc (110 K) and HT Cc (250 K) structures of complex 1.34 a) Representation of the asymmetric unit with distorted [MnN₄O₂]⁺ units shown as polyhedra with colour coding: HS1 (red), HS2 (yellow), LS1 (blue) and LS2 (green). b) The same structures displayed in a layered crystal packing arrangement, showing the relationships between the conventional unit cells of each. c) Simplified representation of the three structures in terms of the Mn atoms alone, with the same colour coding as in (a,b). Atoms are shown at 50 % atomic probability distributions for ellipsoids. BPh₄ ⁻ anion in (b), (c) and hydrogen atoms are omitted for clarity.
