Inorganic anion-dependent assembly of zero-, one-, two- and three-dimensional Cu(II)/Ag(I) complexes under the guidance of the HSAB theory: Synthesis, structure, and magnetic property

A Thiacalix Basket and Its Anion‐Dependent 2‐D and 3‐D Silver(I) Coordination Polymers via Exo‐Coordination

“…In general, unlike above results, coordinating anions lead the formation of higher dimensional products than non‐coordinating anions . The conformations of the S 4 ‐platform for the free L , 1 , and 2 show that the conformational changes upon complexation are negligible due to the highly rigid nature of the basket (see the simplified green twisted squares in Figure ).…”

Mixed-Metal Coordination Polymers and Molecular Squares Based on a Ferrocene-Containing Multidentate Ligand 1,2-Di(4-pyridylthio)ferrocene

“…Furthermore, the coordination modes are consistent with the hard soft acids and bases (HSAB) theory. , Ni II , Co II , and Cu II ions coordinated with only pyridine moieties (complexes 1 , 2 , and 4 ), while Ag I and Cu I ions, which are soft acids, also coordinated with the soft base thioether moiety (complexes 5 – 7 ). Complex 3 is exceptional in that it has no Ag–S bonds despite containing the Ag I ion.…”

Novel and high photovoltaic performance sensitizers of copolymeric sulfur coordination metal complexes of benzimidazolyl benzodithiophene derivatives

“…In recent years, metal complexes with N and O as coordinating atoms have been used as auxiliary electron acceptors, and their PCE has been increased to near 10%, but still not more than 10%, and it is also found that the stronger the coordination bond energy of the metals (Ni(II), Cu(II), Zn(II), Cd(II), and Hg(II)) with the coordinating atoms N and O is, the higher the PCE is ref. 37-40. According to the soft and hard acid-base principle, 41,42 S atom is a softer base than O and N atoms, and the complexes of S coordinating with soft acids (Ni(II), Cu(II), Zn(II), Cd(II), and Hg(II)) will have stronger coordination bonds than those with O and N, this will facilitate the enhancement of the electron-withdrawing ability of the auxiliary electron acceptors (A 0 ) and improve the push-pull electron balance within the sensitizer molecule, thereby improving the absorption of spectral range and intensity of the sensitizer and enhance the photovoltaic performance.…”
