摘要
Hybrid compounds [NaCr(ox)(3)](2)[Ni(cyclam)][Ni(cyclam)(H2O)(2)](.)8 H2O (1) and [NaCr(ox)(3)][Cu(tren)(H2O)](.)3 H2O (2) are assembled in MeCN/H2O from the reaction of Na-3[Cr(ox)(3)](.)5 H2O with [Ni(cyclam)](CIO4)(2) and [Cu(tren)](PF6)(2), respectively, where cyclam = 1,4,8,11-tetraazacyclotetradecane and tren = tris(2-aminoethyl)amine. In 1 and 2, Ni(II) macrocyclic complex and Cu(II) complex, respectively, are intercalated between the anionic 2D layers of [NaCr(ox)(3)](n)(2n-). The magnetic susceptibility data of I and 2, measured in the temperature range 5-301 K, indicate weak ferromagnetic interactions (theta = 1.9 K for 1 and 0.29 K for 2) between the Cr(III) ions in the 2D layers and the intercalated paramagnetic metal complexes.
