| Abstract: | Three open-framework metal oxalates, formulated as (Hdbu)In2(OH)(ox)3] (1), (Hthfa)Eu2(Hthfa)(H2O)(ox)4]? 3H2O (2), and (Hepc)Bi(ox)2] (3), were prepared under solvent-free conditions, where dbu = 1,8-diazabicyclo5.4.0]undec-7-ene, ox = oxalate, thfa = tetrahydrofurfurylamine, and epc = 4-ethylpiperazine-1-carbaldehyde. Topological analyses reveal that these compounds have different 4-connected networks with sra (for 1), lon (for 2), and dia (for 3) topologies. Compound 2 displays a bright red luminescence as a result of excitation at 397 nm. |
