文摘
The abrupt [HS-HS] 鈫?localized [HS-LS] spin crossovers of a new triazole-based diiron(II) complex result in a record-equaling thermal hysteresis loop width for a dinuclear complex (螖T = 22 K by SQUID magnetometer in 鈥渟ettle鈥?mode) and show a remarkable scan rate dependence of only the cooling branch, as revealed by detailed magnetic, DSC, and M枚ssbauer studies.
