Abstract:
Hydrothermal reaction of the metalloligand {[Co(Pzdc) 2 ] · 2H 2 O} n ( 1 ) with Ce(NO 3 ) 3 · 6H 2 O yields a heterometallic 3d‐4f coordination compound {[Ce 2 Co(Pzdc) 4 (H 2 O) 6 ] · 2H 2 O} n ( 2 ) (H 2 Pzdc = 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 Co II –Ce III herringbone structure, in which the slightly deformational 1 and central Ce III atoms are linked by Pzdc 2– spacers, and is further analyzed with {4.6 2 } 2 {4 2 .6 2 .8 2 }{6 3 } 2 {6 5 .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.
