“…Inorganic-organic hybrid iodoplumbates have greatly attracted scientists' attention in recent years due to their diverse structures and significant excitonic, nonlinear optical and other physical properties [1][2][3][4][5][6][7]. Their abundant structural diversity, including zero-dimensional clusters, infinite chains, layered perovskites, and three-dimensional polymeric networks, results from the flexibility of the Pb 2+ coordination geometry and the characteristics of iodide anions [2,[7][8][9][10][11][12][13][14][15][16]. The structures of iodoplumbates are usually made up of [PbI 6 ] octahedra by sharing vertexes, edges, or faces.…”

The design and synthesis of heterometallic iodoplumbates have attracted much interest due to the diverse structures and significant physical properties. A Pb/CuI/I heterometallic iodoplumbate, [PbCu2I4(bipy)]n (1) (bipy = 2,2′-bipyridine), has been synthesized by solvothermal reaction of PbI2, Cu(NO3)2, bipy, and HI, and characterized by single-crystal X-ray diffraction, powder X-ray diffraction, and thermogravimetric analysis. This compound exhibits one-dimensional neutral structure, which is built upon the linkages of Pb/I chains, Cu/I chains, and Cu(bipy) units. The yellow compound has an optical bandgap of 2.32 eV and shows fluorescent emission at 610 nm which is assigned to iodide-to-copper charge transfer.

Eight new sulfur-based coordination compounds ranging from 0D to 2D have been designed and synthesized. These compounds were created using bidentate flexible ligands based on methimazole with varying spacers of 2, 3, or 5 methylene groups (termed L 2 , L 3 , and L 5 ). These compounds includeIn the case of 1D polymers 1, 5, 6, and 7 with bridging bidentate ligands, the halides have not contributed to the expansion of the structures. In the centrosymmetric dimeric compound 2, with terminal chlorine groups, one of the ligands bridging two Zn(II) ions, while the other two display a chelating coordination mode. In the dimeric species of 3, the Cd(II) ions are connected by two bridging azides, while the remaining coordination sites of five-coordinate metal ions are satisfied by a chelating mode of the ligand and a terminal azide group, preventing the expansion of the structure. In the monomeric structure of 4, neither the ligand nor the halides are in their bridging mode. The longer spacer length of the ligand in 8 and the use of uncoordinated ClO 4 − anions lead to the formation of a 2D sulfur-rich structure with hca topology. These compounds were examined for their ability to adsorb iodine in both the vapor and solution phases. The maximum iodine uptake capacity in the solution ranged from 196.72 to 801.33 mg/g, setting an incredible record for such nonporous adsorbents. The effects of azide and chlorine on the geometry, electronic structures, and iodine adsorption capacity of complexes 3 and 4 were studied by using density functional theory (DFT) at the B3LYP/6-31G(d,p)/LANL2DZ level in both gas and solvent. These results were then compared with experimental data.

Mixed-valence copper(I/II) atoms have been introduced successfully into a Pb/I skeleton to obtain two heterometallic iodoplumbates, namely poly[bis(tetra-n-butylammonium) [bis(μ-dimethyldithiocarbamato)dodeca-μ-iodido-hexa-μ-iodido-tetracopper(I)copper(II)hexalead(II)]], {(CHN)[CuCuPb(CHNS)I]}, (I), and poly[[μ-iodido-tri-μ-iodido-iodido[bis(1,10-phenanthroline)copper(I)]copper(I)copper(II)lead(II)] hemiiodine], {[CuCuPbI(CHN)]·0.5I}, (II), under solution and solvothermal conditions, respectively. Compound (I) contains two-dimensional anionic layers, which are built upon the linkages of Cu(SCNMe) units and one-dimensional anionic Pb/I/Cu chains. Tetra-n-butylammonium cations are located between the anionic layers and connected to them via C-H...I hydrogen-bonding interactions. Compound (II) exhibits a one-dimensional neutral structure, which is composed of [PbI] square pyramids, [CuI] tetrahedra and [CuNI] trigonal bipyramids. Face-to-face aromatic π-π stacking interactions between adjacent 1,10-phenanthroline ligands stabilize the structure and assemble compound (II) into a three-dimensional supramolecular structure. I molecules lie in the voids of the structure.
