Complex assembly preferences and resultant spin state choice and Jahn-Teller distortion mode in twelve Mn(III) complexes of varying nuclearity with Schiff base chelate ligands of different sizes are compared. Mononuclear complexes [Mn(5-F-Sal₂323)]OTf (1), [Mn(5-F-Sal₂323)]ClO₄ (2) and [Mn(5-F-Sal₂323)]NO₃, (3) with the 8-carbon R-Sal₂323 chelate type show rare axial compression at room temperature and complexes (2) and (3) also show reversible thermal spin state switching from spin quintet to triplet states on cooling. The prevalence of atypical axial compression is further probed by single crystal diffraction studies on high spin mononuclear complexes (4)-(7) with the longer 9-carbon R-Sal₂333 chelate series using [Mn(3-OEt-Sal₂333)]BF₄, (4) [Mn(3,5-diOMe-Sal₂333)]BF₄·0.5PrOH, (5), [Mn(5-F-Sal₂333)]BPh₄, (6) and [Mn(5-NO₂-Sal₂333)]BPh₄, (7) as examples.
