Four new complexes, {[M(NAIP)(H2O)4]·2H2O}n (M = Co (1), M = Mn (2)), {[Zn(NAIP)]·0.5H2O}n (3) and {Cd(NAIP)(H2O)2]·1.5H2O}n (4) [H2NAIP = 5-(nicotinamido)-isophthalic acid] have been prepared and structurally characterized. The ligand NAIP2− exhibits different coordination modes and leads to the formation of various architectures. Complexes 1 and 2 show a one-dimensional (1D) zigzag chain, where hydrogen-bonding interactions further link these chains to a three dimensional (3D) supramolecular structure. For complex 3, a 3D coordination network with a four-coordinated Zn(II) and NAIP2− as a SBU was observed. Complex 4 presents a three-connected 2-fold interpenetrated 3D network with a (10, 3)-b net topology. Their luminescent and magnetic properties have been investigated in the solid state.
Graphical abstractFour new coordination polymers with 5-(nicotinamido) isophthalic acid have been synthesized and characterized. Differences in the ligation modes of the ligand and the coordination numbers of the metal ions resulted in 1D and 3D structures for 1/2 and 3/4, respectively. The luminescent and magnetic properties of these complexes were investigated.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Four new complexes with 5-(nicotinamido)-isophthalic acid have been prepared and structurally characterized. ► The ligand display different coordination modes at the different metal ion. ► Weak interaction assisted three-dimensional supramolecular structure. ► Magnetic properties. ► Zn(II) and Cd(II) complexes show strong blue emission in solid state.
