Synthesis and Structural Characterization of Lithium-Based Metal−Organic Frameworks
Two lithium-based metal-organic frameworks, Li{sub 2}(C{sub 14}H{sub 8}O{sub 4}) [Li{sub 2}(4,4'-BPDC) [1]; ULMOF-2, UL = ultralight; BPDC = biphenyldicarboxylate]; space group P2{sub 1}/c, a = 12.758(2) {angstrom}, b = 5.142(4) {angstrom}, c = 8.00(2) {angstrom}, {beta} = 97.23{sup o}, V = 520.6(14) {angstrom}{sup 3} and Li{sub 2}(C{sub 14}H{sub 8}O{sub 6}S) [Li{sub 2}(4,4'-SDB) [2]; ULMOF-3, UL = ultralight; SDB = sulfonyldibenzoate], space group P2{sub 1}/n, a = 5.5480(11) {angstrom}, b = 23.450(5) {angstrom}, c = 10.320(2) {angstrom}, {beta} = 96.47(3){sup o}, V = 1334.1(5) {angstrom}3, were synthesized. Compounds 1 and 2 were synthesized by solvothermal methods and were characterized using single crystal X-ray diffraction. Structure 1 consists of layers of two-dimensional antifluorite related LiO motif connected by BPDC linkers, whereas structure 2 is constructed by a combination of tetrameric lithium polyhedral clusters connected by the sulfonyldibenzoate linker. The frameworks are stable up to 575 and 500 C, respectively, under N{sub 2} atmosphere.
