Abstract: KEYWORDSAn air stable Fe(II) complex of a cyclic β-triketone, 2-acetyl-1,3-indandione (2AID) was obtained in two different ways and studied by Mössbauer spectroscopy. The Mössbauer data at room temperature point to six-coordinated, high spin Fe(II) complex. The temperaturedependent measurements indicate a phase transition in going from 293 to 77 K. Further lowering the temperature, however, do not cause the expected changes for spin-crossover transition. This data provoked application of quantum chemical metho… Show more

“…Despite this, we recovered triketone 1 free from metal and other impurities, as evidenced by both 1 H NMR (fig. S28) and inductively coupled plasma optical emission spectrometry (ICP-OES) analysis, which is notable, given the propensity for some triketones to coordinate metals ( 38 ). After depolymerization PDK 1 , we then deconstructed the remainder of the assembly at 60°C in strong acid, isolating metal from glass and separating triketone 4 from TREN using solid-liquid separations.…”
