The structural, phonon and optical properties of [CH3NH3]M0.5CrxAl0.5−x(HCOO)3 (M = Na, K; x = 0, 0.025, 0.5) metal–organic framework perovskites for…

We report the structural, phonon and luminescence studies of six heterometallic perovskite-type metal–organic frameworks (MOFs) templated by methylammonium cations (CH3NH3+ and MeA+) with the following formulae: [MeA]Na0.5Cr0.5(HCOO)3 (MeANaCr), [MeA]K0.5Cr0.5(HCOO)3 (MeAKCr), [MeA]Na0.5Al0.5(HCOO)3 (MeANaAl), [MeA]K0.5Al0.5(HCOO)3 (MeAKAl), [MeA]Na0.5Cr0.025Al0.475(HCOO)3 (MeANaAlCr, 5 mol% of Cr3+ ions) and [MeA]K0.5Cr0.025Al0.475(HCOO)3 (MeAKAlCr, 5 mol% of Cr3+ ions). All of them crystallise in a monoclinic system (P21/n space group) with one MeA+ cation in an asymmetric unit forming four medium-strength hydrogen bonds (HBs) with a metal-formate framework. The DSC measurements and XRD s…

Novel bimetallic MOF phosphors with an imidazolium cation: structure, phonons, high- pressure phase transitions and optical response

2018

We report the synthesis, crystal structure, phonons and luminescence properties of three novel heterometallic metal organic frameworks (MOFs) with perovskite-like topology of the following formulas: [C3H5N2]Na0.5Cr0.5(HCOO)3 (ImNaCr), [C3H5N2]Na0.5Al0.5(HCOO)3 (ImNaAl) and [C3H5N2]Na0.5Al0.475Cr0.025(HCOO)3 (ImNaAlCr with 5 mol% of Cr3+). ImNaCr crystallizes in a monoclinic system (P2/n space group) with one imidazolium cation (Im+) in an asymmetric unit forming six N–H⋯O and four C–H⋯O hydrogen bonds. In contrast to other known heterometallic MOFs, the complete substitution of Cr3+ ions with smaller Al3+ ions leads to a change of the crystal symmetry. ImNaAl adopts a monoclinic P21/n space…
