Structural and magnetic properties of Co3(dpa)4Br2†
Abstract
Eleven crystal structures have been determined for the trinuclear Co3(dpa)4Br2 (1) (dpa = di(2-pyridyl)amide anion) molecule in the following solvates: 1·CH2Cl2 (at 111, 147 and 240 K), 1·C6H12 (at 110, 150, 213 and 298 K) and 1·1.75C7H8·0.5C6H14 (at 110, 170, 213 and 295 K). Their magnetic behavior has been measured over the temperature range 5–350 K. In nearly every respect their behavior closely parallels that of their
