Bhargao, Pooja H. published the artcileSynthesis and structural characterization of a barium coordination polymer based on a μ2-monoatomic bridging 4-nitrobenzoate, SDS of cas: 123-39-7, the main research area is crystal structure barium nitrobenzoate methylformamide coordination polymer; barium nitrobenzoate methylformamide polymer preparation fluorescence thermal decomposition.
The synthesis, spectral characterization, crystal structure and properties of [Ba(H2O)2(NMF)2(4-nba)2], (1; NMF = N-methylformamide; 4-nba = 4-nitrobenzoate), are reported. 1H and 13C NMR spectral data reveal NMF in 1. A strong band at 1660 cm-1 in the IR spectrum indicates the binding of amide O to Ba(II) which is confirmed by the single crystal structure. The unique Ba(II) in situated on a mirror plane exhibits nine coordination and is bonded to two symmetry related monodentate terminal NMF ligands via the amide O, and a terminal aqua ligand. The μ2-monoat. bridging binding mode of each of a crystallog. independent 4-nba ligand and a unique H2O ligand link the Ba(II) cations into an infinite chain extending along a, giving a 1-dimensional coordination polymer with Ba···Ba separations of 4.2522(3) Å. In the chain, the {BaO9} polyhedra are linked in a face sharing fashion. Thermal decomposition of gave BaCO3 residue. A comparative study of the structural chem. of several Ba coordination polymers is described.
Journal of Coordination Chemistry published new progress about Crystal structure. 123-39-7 belongs to class amides-buliding-blocks, name is N-Methylformamide, and the molecular formula is C2H5NO, SDS of cas: 123-39-7.
