Cover Story: The chiral complex cations in [Mn(en)3](NO3)2 and [Co(en)3](NO3)2 spontaneously resolve to form a mixture of conglomerate crystals, crystallizing in the hexagonal space group P6322 at room temperature. Like the previously-reported Ni(II) and Zn(II) congeners, the Mn(II) analogue undergoes a thermally-induced reversible phase transition to enantiomorphic space group P6522 or P6122, resulting in a tripling of the crystallographic c parameter and the emergence of a gentle helicity in the position of the metal atoms. Conversely, a phase transition was not observed for the Co(II) derivative. Synthesis and characterization by a variety of variable-temperature methods, including single-crystal and powder X-ray diffraction, Raman spectroscopy, differential scanning calorimetry, heat capacity, and magnetic susceptibility measurements, are reported.
