Divalent Cobalt

We report on the synthesis and the characterization of a novel cobalt trimesate metal-organic framework, designated as KCL-102. Powder X-ray diffraction pattern of KCL-102 is dominated by a reflection at 10.2° (d-spacing = 8.7 Å), while diffuse reflectance UV-Vis spectroscopy indicates that the divalent cobalt centers are in two different coordination geometries: tetrahedral and octahedral. Further, the material shows low stability in humid air, and it transforms into the well-known phase of hydrous cobalt trimesate, Co3(BTC)2·12H2O. We associated this transition with the conversion of the tetrahedral cobalt to octahedral cobalt.

Solvothermal Conditions

Reactions between triazatruxene-based tricarboxylate ligands, H3tat-R, and zinc nitrate under solvothermal conditions afforded new metal–organic frameworks (MOFs) with the general formula [Zn3(tat-R)2(H2O)2], MUF-tat-R (R=a hydrocarbon substituent on the triazatruxene nitrogen atoms). Single-crystal X-ray diffraction analysis revealed that these frameworks are 3D networks with a (10,3)-a topology. Linear trinuclear zinc clusters are connected to tat ligands to form chiral channels that accommodate the substituents on the tat ligands. MUF-tat and MUF-tat-benzyl crystallize in a cubic crystal system whereas MUF-tat-butyl and MUF-tat-hexyl are tetragonal. MUF-tat-benzyl retains its porosity on activation, which was confirmed by gas adsorption studies.

In this study, lanthanide metal-organic frameworks Ln(BTC)(DMF)2(H2O) (LnMOFs) are synthesized using the metal nitrates as lanthanide (Ln = La, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, Yb and Lu) source and 1,3,5-benzenetricarboxylic acid (BTC) as a coordination ligand. X-ray diffraction (XRD) analysis, Fourier-transform infrared spectroscopy (FTIR), thermogravimetric (TG/DTG) analysis fluorescence spectroscopy (FLS), and scanning electron microscopy (SEM) are employed to characterize the newly synthesized LnMOFs.
