“…For example, the intercalation of small cations onto the B-site could accompany reduction of Fe 3+ to Fe 2+ . Noting the octahedral coordination of Na + by formate in NaMn(HCOO) 3 , one might infer the accessibility of mixed-valent Na + -intercalates such as [C(NH 2 ) 3 ]Na 1/3 Fe 2/3 2+/3+ (HCOO) 3 . Likewise the proton conductivity behavior of other formates might be enhanced by vacancies.…”

Ordered B-Site Vacancies in an ABX₃ Formate Perovskite

We report the synthesis and structural characterisation of a series of aliovalently doped metal-formate ABX3 perovskite frameworks [C(NH2)3]Mn 2+ 1−x (Fe 3+ 2x/3 , x/3)(HCOO)3 (= B-site vacancy). For sufficiently large x, the vacancies order, lowering the crystal symmetry from orthorhombic P nna to monoclinic P 2/n. This system establishes B-site vacancies as a new type of defect in formate perovskites, and one with important chemical, structural, and functional implications. Monte Carlo simulations driven by a nearestneighbour vacancy repulsion model show checkerboard vacancy order to emerge for x > 0.6, in accord with experiment.

One‐Pot Multiple Metal–Organic Framework Formation: Concomitant Generation of Structural Isomers or of Drastically Distinct Materials

et al. 2014

The solvothermal reaction of 2,5‐dihydroxyterephthalic acid (H2dhtp) and magnesium(II) nitrate in N,N‐dimethylformamide (DMF) led to the simultaneous formation of two structural isomers, namely, the lvt network Mg(dhtp)(dmf)2 (1) and the compound Mg3(dhtp)3(dmf)6·0.75H2O (2) with the pcu α‐Po primitive cubic topology. The same reaction conditions with manganese(II) nitrate and terephthalic acid (H2tp) resulted in the concomitant generation of two drastically different metal–organic frameworks (MOFs), namely, Mn2(tp)2(dmf)2 (3) and [Mn(HCOO)3][NC2H8] (4), in which the formato ligands and N,N‐dimethylammonium cations arise from DMF degradation.
