Abstract
AbstractHydrothermal reaction of the metalloligand {[Co(Pzdc)2]·2H2O}n (1) with Ce(NO3)3·6H2O yields a heterometallic 3d‐4f coordination compound {[Ce2Co(Pzdc)4(H2O)6]·2H2O}n (2) (H2Pzdc = pyrazine 2, 3‐dicarboxylic acid). X‐ray structure determination, IR spectroscopy, elemental analysis, thermogravimetric analysis, and magnetic property for the targets are presented. Compound 1 affords one‐dimensional double zigzag chains. Compound 2 features a three‐dimensional CoII–CeIII herringbone structure, in which the slightly deformational 1 and central CeIII atoms are linked by Pzdc2– spacers, and is further analyzed with {4.62}2{42.62.82}{63}2{65.8}2 topology symbol. Magnetic property analysis reveals that the antiferromagnetic interactions occur in compound 2 due to a long‐range superexchange pathway between adjacent magnetic centers. In addition, the solid state photoluminescence of 2 was investigated.
