| Abstract: Two novel heterotrimetallic 1D zigzag chain coordination polymers, {[Cu(Me2valpn)Dy(DMF)2(H2O)Fe(CN)6]·1.5H2O·0.5CH3OH}n (1) and {[Cu(Me2valpn) Tb(DMF)2(H2O)Fe(CN)6]·H2O·CH3OH}n (2) (H2Me2valpn=N,N'-bis(3-methoxysalicylidene)-2,2-dimethyl-1,3-diaminopropane), were prepared by stepwise synthetic approach. Single -crystal X-ray diffraction analysis revealed that each[Fe(CN)6]3- is connected with two[Cu(Me2valpn)]Ln(DMF)2(H2O)]3+ fragments in a cis-mode. Accordingly, there are two types of bent bridging linkages (Fe-C≡N-Cu and Fe-C≡N-Ln) in the chain besides the diphenoxo bridges between Cu(II) and Ln(III). In the temperature range of 9.5~300 K, the dc magnetic susceptibilities of complex 1 are consistent with the Curie-Weiss law and give positive Curie-Weiss constants (θ=13.17 K), indicating the presence of predominant ferromagnetic interactions. The AC magnetic measurements reveal that complex 1 shows no slow magnetization relaxation. |
