本文报道了水合氟化铬、碳酸铜和戊酸在1,4,7,10 -四氮杂环十二烷（环）存在下反应合成的具有31个顺磁中心的有限链。磁性研究表明，主要是反铁磁交换导致了高密度的低洼自旋态和大的饱和场。
A finite chain of thirty‐one paramagnetic centers is reported, synthesized by reaction of hydrated chromium fluoride, copper carbonate and pivalic acid in the presence of 1,4,7,10‐tetrazacyclododecane (cyclen). Magnetic studies show predominantly anti‐ferromagnetic exchange leading to a high density of low‐lying spin states and large saturation field.
