Low-temperature magnets M[N(CN)(2)](2)(pyrimidine) (M = Fe and Co) with a 3-D network
X-Ray crystal structure analyses reveal that the title complexes have a 3-D network, in which N(CN)(2)(-) and pyrimidine contribute mu -1,5-bridged 2-D and mu -1,3-bridged 1-D structures, respectively. Magnetic measurements indicate that the Fe and Co complexes have spontaneous magnetizations below the transition temperatures of 3.2 and 1.8 K, respectively.
