Abstract [en]

The bifunctional linker molecule [5-(phosphonomethyl)-2,4-bis(sulfonomethyl)phenyl]methanesulfonic acid (HO3S-CH2)(3)-C6H2-CH2PO3H2 (abbreviated as H(5)L4) was employed in systematic high-throughput investigations in order to discover new coordination polymers (CPs). Employing 27 metal salts of 17 different metals in this investigation, five new compounds [Mg-2(HL4)(H2O)(6)] (1), [Pb-4(L4)(OH)(3)] (2), [Ba-2(H(2)L4)(OH)(H2O)] (3), [Ba-2(HL4)(H2O)(4)] (4), and [Cd-2,Cd-5(L4)(H2O)(7)] (5) were discovered and their crystal structures were determined. In all compounds, the sulfonate and phosphonate groups could not be resolved since the P and S atoms are statistically occupying the atom site with a ratio of 0.25 to 0.75. This is reflected in the P-O and S-O bond lengths. Four of the structures were determined from single-crystal X-ray diffraction data, whereas the structure of 4 was solved ab initio from powder data using real-space methods and refined using Rietveld methods.
