The facile aqueous medium reactions of Cu(II) nitrate with BES biobuffer [(HOCH2CH2)2N(CH2CH2SO3H), hereinafter referred as H3bes] in the presence of various benzenecarboxylic acids [benzoic (Hba), 3-hydroxybenzoic (Hhba), and 3,5-dihydroxybenzoic (Hdhba) acid] and LiOH gave rise to the self-assembly generation of three new heterometallic CuII/Li materials, [Li(H2O)4][Cu4(¦Ì2-Hbes)4(¦Ì2-ba)]¡¤H2O (1) and [Cu4(¦Ì3-Hbes)4(L){Li(H2O)2}]n¡¤3nH2O {L = ¦Ì2-hba (2) and ¦Ì2-dhba (3)}. They were isolated as air-stable crystalline solids and fully characterized by IR and UV-visible spectroscopy and electrospray ionization (ESI)-MS(¡À), elemental, thermal, and single-crystal x-ray diffraction analyses. The latter revealed that 1–3 have comparable packing patterns and unit cell parameters, being composed of similar [Cu4(¦Ì-Hbes)4(¦Ì-carboxylate)]– cores and [Li(H2O)4]+ cations (in 1) or [¦Ì-Li(H2O)2]+ groups (in 2 and 3), which are arranged into discrete 0-dimensional aggregates in 1 or infinite 3-dimensional noninterpenetrating metal-organic networks in 2 and 3. The topol. anal. of the coordination polymers 2 and 3 disclosed the trinodal 3,3,4-connected underlying nets with an unprecedented topol. defined by the point symbol of (4.6.8)4(42.6)2(62.162.182), further simplification of which resulted in the binodal 4,4-connected nets with the pts (PtS) topol. Apart from representing very rare examples of coordination compounds derived from H3bes, 1–3 feature solubility in H2O and were applied as efficient and versatile catalyst precursors for the mild (60¡ã) single-pot hydrocarboxylation, by CO and H2O, of various gaseous, linear, and cyclic Cn (n = 2-9) alkanes into the corresponding Cn+1 carboxylic acids, in H2O/MeCN medium under homogeneous conditions and in the presence of K peroxodisulfate. Total yields (based on alkane) of carboxylic acids up to 78% were achieved, which are remarkable in the field of alkane functionalization under mild conditions, especially for a C-C bond formation reaction in aqueous acid-solvent-free medium.
