WebWe report a new one-dimensional tube-like atomically precise silver-thiolate polymer–chain. The structure consists of Ag14(SR)18 as the building units. Silver atoms are linked with the thiol ligand to form the one-dimensional structure. The non-covalent interactions like argentophilic and C–H···H–C interactions appear as crucial for the long-range structural … WebThe structure is refined to the final R = 5.0% in the anisotropic approximation of atomic displacement parameters using 3742 F > 3σ(F). The idealized formula (Z = 3) is Na 37Ca 10Mn 2FeZr 6Si 50(Ti, Nb) 2O 144(OH) 5Cl 3 · H 2O. Like other 24-layer min-erals of the eudialyte group, this mineral has a modula r structure. Its structure contains ...
