Figure 3
A plot of χMT versus T for (1-Fe) (open circles) and concomitant variation of the MII—N distances for (1-Fe) (squares) and (1-Zn) (filled circles). The γHS value (crosses) is the molar fraction of HS molecules derived from the Mössbauer experiment. The transition temperature T1/2 = 233 K is marked by the vertical dashed line. |
