【 摘 要 】

Three new 3D metal–organic frameworks of lanthanum based on mixed anionic ligands, [(La₂(pQ)₂(BDC)₄)·4DMF]_n, [(La₂(pQ)₂(DHBDC)₄)·4DMF]_n, [(La₂(CA)₂(BDC)₄)·4DMF]_n (pQ—dianion of 2,5-dihydroxy-3,6-di-tert-butyl-para-quinone, CA—dianion of chloranilic acid, BDC-1,4-benzenedicarboxylate, DHBDC-2,5-dihydroxy-1,4-benzenedicarboxylate and DMF-N,N′-dimethylformamide), were synthesized using solvothermal methodology. Coordination polymers demonstrate the rare xah or 4,6T187 topology of a 3D framework. The homoleptic 2D-coordination polymer [(La₂(pQ)₃)·4DMF]_n was obtained as a by-product in the course of synthetic procedure optimization. The thermal stability, spectral characteristics and porosity of coordination polymers were investigated.
