Abstract

In order to synthesize new coordination polymers with original architectures and interesting magnetic properties, we used the nitranilate ligand (C6O4(NO2)22− = C6N2O82−), derived from the dianionic ligand dhbq2− (2,5-dihydroxy-1,4-benzoquinone = H2C6O42−). The use of this bis-bidentate bridging ligand led to [(DAMS)2{FeNa(C6N2O8)3}·CH3CN]n (1) (DAMS+ = C16H17N2+ = 4-[4-(dimethylamino)-α-styryl]-1-methylpyridinium), a 2D heterometallic coordination polymer presenting an unprecedented structure for any anilato-based compound. This structural type is a 3,6-connected 2D coordination polymer derived from the well-known honeycomb hexagonal structure, where Fe(III) ions alternate with Na+ dimers (as Na2O12 units) in the vertices of the hexagons and with an additional [Fe(C6N2O8)3]3− anion located in the center of the hexagons connecting the three Na+ dimers. The magnetic properties of compound 1 show the presence of paramagnetic isolated high spin Fe(III) complexes with a zero field splitting, |D| = 8.5 cm−1. View Full-Text
