Postsynthetic installation of lanthanide cubanes into a metallosupramolecular framework via a single-crystal-to-single-crystal (SCSC) transformation is presented. Soaking single crystals of K6[Rh4Zn4O(l -cys)12] (K6[ 1 ]; l -H2cys=l -cysteine) in a water/ethanol solution containing Ln(OAc)3 (Ln3+=lanthanide ion) results in the exchange of K+ by Ln3+ with retention of the single crystallinity, producing Ln2[ 1 ] ( 2Ln ) and Ln0.33[Ln4(OH)4(OAc)3(H2O)7][ 1 ] ( 3Ln ) for early and late lanthanides, respectively. While the Ln3+ ions in 2Ln exist as disordered aqua species, those in 3Ln form ordered hydroxide-bridged cubane clusters that connect [ 1 ]6− anions in a 3D metal-organic framework through coordination bonds with carboxylate groups. This study shows the utility of an anionic metallosupramolecular framework with carboxylate groups for the creation of a series of metal cubanes that have great potential for various applications, such as magnetic materials and heterogeneous catalysts. 相似文献

Postsynthetic installation of lanthanide cubanes into a metallosupramolecular framework via a single‐crystal‐to‐single‐crystal (SCSC) transformation is presented. Soaking single crystals of K6[Rh4Zn4O(l ‐cys)12] (K6[ 1 ]; l ‐H2cys=l ‐cysteine) in a water/ethanol solution containing Ln(OAc)3 (Ln3+=lanthanide ion) results in the exchange of K+ by Ln3+ with retention of the single crystallinity, producing Ln2[ 1 ] ( 2Ln ) and Ln0.33[Ln4(OH)4(OAc)3(H2O)7][ 1 ] ( 3Ln ) for early and late lanthanides, respectively. While the Ln3+ ions in 2Ln exist as disordered aqua species, those in 3Ln form ordered hydroxide‐bridged cubane clusters that connect [ 1 ]6? anions in a 3D metal‐organic framework through coordination bonds with carboxylate groups. This study shows the utility of an anionic metallosupramolecular framework with carboxylate groups for the creation of a series of metal cubanes that have great potential for various applications, such as magnetic materials and heterogeneous catalysts. 相似文献

The crystal structures of five new transition‐metal complexes synthesized using thiazole‐2‐carboxylic acid (2‐Htza), imidazole‐2‐carboxylic acid (2‐H2ima) or 1,3‐oxazole‐4‐carboxylic acid (4‐Hoxa), namely diaquabis(thiazole‐2‐carboxylato‐κ2N,O)cobalt(II), [Co(C4H2NO2S)2(H2O)2], 1 , diaquabis(thiazole‐2‐carboxylato‐κ2N,O)nickel(II), [Ni(C4H2NO2S)2(H2O)2], 2 , diaquabis(thiazole‐2‐carboxylato‐κ2N,O)cadmium(II), [Cd(C4H2NO2S)2(H2O)2], 3 , diaquabis(1H‐imidazole‐2‐carboxylato‐κ2N3,O)cobalt(II), [Co(C4H2N2O2)2(H2O)2], 4 , and diaquabis(1,3‐oxazole‐4‐carboxylato‐κ2N,O4)cobalt(II), [Co(C4H2NO3)2(H2O)2], 5 , are reported. The influence of the nature of the heteroatom and the position of the carboxyl group in relation to the heteroatom on the self‐assembly process are discussed based upon Hirshfeld surface analysis and used to explain the observed differences in the single‐crystal structures and the supramolecular frameworks and topologies of complexes 1 – 5 . 相似文献

Five new molecular complexes of chemical formula [M(4-tza)2(H2O)2] (M = Co, Ni, or Cu) and a complex of [Cu(4-tza)2]·4H2O using thiazole-4-carboxylic acid (4-tza) as the ligand have been successfully synthesized and structurally characterized by single crystal X-ray diffraction. Two district polymorphs (α and β) are found for both [Co(4-tza)2(H2O)2] and [Ni(4-tza)2(H2O)2]. The effects of solvent composition and temperature on the formation of these polymorphs have been investigated and phase behaviour of the polymorphs was studied through X-ray powder diffraction. Unlike the complexes of Co and Ni, [Cu(4-tza)2(H2O)2] does not display polymorphism but exhibits irreversible structural transformation from [Cu(4-tza)2(H2O)2] to the dehydrated form, [Cu(4-tza)2], upon heating. 相似文献
