Hyperfine interactions have been studied at a cooperative 'T2 = ' Al transition in the solid complex Fe(4,7-(CH&-pher&(NCS)z employing an external field Helt = 40 kG and temperatures between 4.2 and 163OK (phen = l,iO-phenanthroline). At cryogenic temperatures, the isolated 'Al ground state may be

Based on measurements of differential scanning calorimetry, the first-order character of the spin-state transition in Fe(bt),(NCS), is established (bt = 2,2'-bi-2-thiazoline). The transition arises at T, ' =180.9 K and T,l =171.2 K, and is characterized by AH = 9.55 kO.7 kJ mol-' and AS = 54.5 \*4 J

A maximum in C, is observed at & due to the &t-order character of the spin-state transition. The value of C,, for high-spin states is greater than that for low-spin states. The derived values
