Coordination and supramolecular network entanglements of organodisulfonates

Synthesis and Structural Studies of Three‐Dimensional Supramolecular Motifs Derived from Neutral and Cationic Zinc Alkanesulfonates

“…The application of noncovalent interactions such as hydrogen bonds, anion ··· π, and π ··· π stacking in coordination chemistry has offered useful alternative strategies for the construction of supramolecular motifs . The cumulative effects of secondary interactions are pivotal to the stability of higher‐dimensional structures, and these interactions provide flexibility to porous frameworks.…”

Synthesis and characterization of a novel 2D zinc(II) coordination polymer

“…Metal-organic frameworks (MOFs) have attracted much attention in recent years owing to the potential functions, such as molecular absorption, ion exchange, fluorescence, electrical conductivity, magnetism, optical properties, gas storage and heterogeneous catalysis [1][2][3][4][5][6][7]. The design and synthesis of novel coordination polymers receive great current interest owing not only to their potential applications [8], but also to their intriguing variety of architectures and topologies [9].…”

“…Single crystal X-ray determination shows that complex 1 consists of two Zn atoms and six tetrazolyl ligands in the crystallographically asymmetric unit with orthorhombic space group Pbcn, each Zn center is linked to three other Zn centers through the bridging ligands. And the dielectric constants of 1 were measured at different temperature, and deuterated effect at the lowest frequency (10 4 Hz) can be estimated to increase 33% at 290 K which was never seen before in the isotope effect.Ó 2009 Elsevier B.V.

Crystal structure of hexaaqua-(μ3-methylenedisulphonato)-bis(μ2- methylenedisulphonato)disamarium(III), Sm2(H2O)6(CH2O6S2)3

“…The coordination chemistry of the sulfonate ion has been less well investigated in comparison with other organic acidato anions such as carbonates and phosphonates [1]. However, by employing disulfonates, which can provide multiple potentially chelating coordination sites, stable networks sustained by sulfonate-metal interactions can be obtained with various dimensionalities [2,3]. The asymmetric unit of the title crystal structure consists of two samarium ions, six coordinating water molecules and three CH 2 2 2− ligand chelates two Sm1 ions simultaneously by using four of its sulfonate oxygens (O7, O8, O10 and O11) into a "paddle-wheel" dimer with an inversion center lying in the middle, and the Sm···Sm distance is 5.348(4) Å.S m2 ions are chelated and bridged through O13−S5−O14 and O16−S6−O18 connectivities into azigzag chain.…”
