“…It is worth mentioning that complex 1 is the first example of a manganese compound with 2,2′-biim and 4,4′-bipy as mixed ligands, although a large number of manganese 2,2′biim and manganese 4,4′-bipy compounds have thus far been reported. [21][22][23] The photoluminescent behaviour of coordination compounds has gained intense attention. [24][25][26] To our knowledge, 2,2′-biim or 4,4′-bipy compounds usually show photoluminescence emissions.…”

A manganese complex with mixed ligands, [Mn(2,2′-biim)2(4,4′-bipy)] n[Mn(2,2′-biim)3]2 n6 n(ClO4)•8 nH2O (2,2′-biim = 2,2′-biimidazole; 4,4′-bipy = 4,4′-bipyridine), has been obtained by a hydrothermal procedure and its structure determined by single-crystal X-ray crystallography. A two-dimensional (2-D) supramolecular layer is established through hydrogen-bonding interactions. Solid-state photoluminescence measurement reveals that this complex shows a blue light emission. Solid-state diffuse reflectance determination uncovers the presence of a narrow optical band gap of 2.18 eV in this complex.

Besides the fact that direct synthesis of oxalate-based Mn(II) complexes did not succeed a lot due to the high insolubility of manganese oxalate (Mn II (C 2 O 4) • 2H 2 O), a new 2D polymeric Mn(II) salt has been synthesized by slow evaporation at room temperature and its structure has been determined by single-crystal X-ray diffraction. The structure was solved by direct methods and refined to conventional agreement indices. The crystal structure is built from anionic, two-dimensional, honeycomb networks formed by the oxalatebridged Mn(II) ions, interleaved by 2,6-diaminopyridinium cations that are entrapped between the layers. The interactions between adjacent layers result from the extended network of intermolecular hydrogen bonds created by the mentioned cations and water molecules. The complex has been fully characterized by single crystal X-ray diffraction, FT-IR and UV-Vis spectroscopy, Rietveld refinement, TGA-DSC analysis and magnetic susceptibility. The title compound exhibits antiferromagnetic coupling between Mn(II) centres.

“…Coordination polymers (also called metal-organic frameworks) are a type of supramolecular complexes containing metal ions linked together by organic bridging ligands (Janiak, 1997(Janiak, , 2003, which have attracted great interest in recent years owing to their potential applications in magnetism, catalysis, gas storage, fluorescence, and gas separation (Janiak and Vieth, 2010;Stylianou et al, 2010;Bloch et al, 2012;Harding and Reynolds, 2012;Hwang et al, 2012;Zheng et al, 2012). Moreover, the design and synthesis of complexes containing two or more neutral amine ligands continue to be a very active research field because of their applications in constructing a variety of supramolecular complexes (Bonnet et al, 2003;Schmittel et al, 2009).…”

A new lead complex, { [Pb(4-sb)(phen)] (4,4 ′ -bipy) 0.5 } n (1) (where 4-sb = 4-sulfobenzoate dianion, phen = 1,10-phenanthroline, 4,4 ′ -bipy = 4,4 ′ -bipyridine), was synthesized and characterized by single-crystal X-ray, infrared, and thermogravimetric analyses and fluorescence studies. In this compound, the lead atom is hexacoordinated by two N atoms of one phen ligand and four O atoms from three 4-sb dianions. Each 4-sb serves as a bridging ligand, connecting adjacent Pb II atoms into a centrosymmetric polymeric chain. Intermolecular π -π interactions and hydrogen bonds are observed in the complex, which stabilize the crystal packing and give rise to three-dimensional architecture.
