X-Ray Crystal Structure of a Novel 2D Mn(II) Coordination Polymer with 4,4′-trimethylenedipyridine and 3-nitrophthalate as Ligands

Аннотация

[Mn₂(μ-4,4′-trimethylenedipyridine)(μ-3-nitrophthalate)₂(H₂O)₄]_n is synthesized using MnCl₂·4H₂O, 4,4′-trimethylenedipyridine, and 3-nitrophthalic acid as starting materials. The complex is investigated by Fourier transform infrared spectroscopy, single crystal X-ray diffraction, elemental analysis, powder X-ray diffraction, diffused reflectance spectroscopy, photoluminescent spectroscop, and thermogravimetric analysis. The complex crystallizes in the orthorhombic system in the space group Aba2 with cell parameters a = 30.1451(10) Å, b = 9.8718(3) Å, c = 11.3258(4) Å, V = 3370.40(19) ų, and Z = 4. The complex exhibits a 2D structure with each Mn(II) atom octahedrally coordinated to three oxygen atoms from two 3-nitrophthalate units, two oxygen atoms from two water molecules, and one nitrogen atom from 4,4′- trimethylenedipyridine.
