%X Systematic
solvent screening using high-throughput solvothermal
syntheses with bismuth nitrate pentahydrate and 1,2,4,5-tetrakis-(4-carboxyphenyl)benzene
(H4TCPB) led to three new porous Bi-metal–organic
frameworks [Bi2(H2TCPB)(TCPB)(H2O)2]·xH2O (CAU-31), (NH2(CH3)2)[Bi(TCPB)(H2O)]·xH2O (CAU-32),
and [Bi4(O)2(OH)2(H2TCPB)(TCPB)(H2O)2]·xH2O (CAU-33). Compounds CAU-31, -32, and -33
were synthesized in CH3OH, CH3OH/DMF, and DMF/toluene,
respectively. The crystal structures were determined using electron
diffraction and single-crystal X-ray diffraction in combination with
the Rietveld method. The structures of CAU-31 and CAU-32 are composed
of isolated Bi3+ ions as the inorganic building unit (IBU),
which are connected by the linker ions to form a layered structure
with inclined interpenetration and a three-dimensional anionic network,
respectively. The IBU of CAU-33 consists of infinite bismuth-oxo rods
forming a three-dimensional network by connection of the organic linkers.
For CAU-33 structural flexibility was observed, and two phases denoted
α- and β-CAU-33 could be isolated.
