Bridging properties of disulfoxide ligands: crystal structure of copper(1,3-bis(n-propylsulfinyl)propane) perchlorate

Novel Lanthanide(III) Coordination Polymers with 1,4-Bis(phenyl-sulfinyl)butane Forming Unique Lamellar Square Array: Syntheses, Crystal Structures, and Properties

“…The construction of organized molecular architectures containing lanthanide ions is a theme of considerable current interest in supramolecular and material chemistry owing to potential applications as new materials . Our studies on the metal complexes with a flexible bis(sulfinyl) show several interesting features for such ligands: their propensity to form multidimensional coordination polymers with both transition metals and rare earth elements in which the metal ions act as nodes forming macrometallocyles, and their preference for O-bonding in “hard acid” metal complexes, such as Ln III , Cu II , 2c, and Sn II , and for σ -bonding ( S -bonding) which is prevalent only in soft Ru III , Pt II , and Pd II complexes. , Such structurally flexible ligands have the possibility to form diverse extended networks which might be influenced and controlled by the length of the spacer units 2c and the template anions. Furthermore, lanthanide networks, especially when studied across the whole series, are relatively unexplored compared to transition metal coordination systems. 1h,i As a continuation of our study, we report herein the syntheses, crystal structures, and luminescent and magnetic properties of a novel series of Ln III coordination polymers with 1,4-bis(phenylsulfinyl)butane ( L , Chart ) that form a unique lamellar square array.…”

N-Benzyl-N-phosphino-tert-butylsulfinamide and Its Coordination Modes with Ir(I), Cu(I), Pd(II), and Pt(II): P,S or P,O?

“…In contrast to the bis-sulfoxide ligand, we did not observe PNSO acting as a bridging ligand to form di-or polynuclear species. 27a,b Indeed BPSP-type ligands have been described to act as μ 2 -Obridging ligands for copper to form polymeric cations [Cu(BPSP) 2 - 25 and S-bridging ligands with P and S atoms in cis positions for [{cis-PtCl 2 (PEt 3 )} 2 (1,2-bis-(phenylsulfinyl)ethane)] bimetallic complexes. 26 Elmann reported an X-ray structure of a CuCl 2 -bis(sulfinyl)imidoamidine (SIAM) complex with a M 2 L 4 -helicate structure, in which each ligand is coordinated to a copper center via the oxygen atom of the sulfinyl group.…”

Novel Five-Connected Lanthanide(III)−Bis(sulfinyl) Coordination Polymers Forming a Unique Two-Dimensional ( , 5) Network

“…The Ln III (Ln = Nd, Yb, corresponding to complexes 1 and 2 ) thiocyanate complexes of L were synthesized by the direct reaction between Ln(NCS) 3 · n H 2 O and L in methanol in the presence of triethyl orthoformate. Both 1 and 2 showed similar IR spectra in which characteristic bands assignable to ν S  O (∼990 cm -1 ) and ν C  N (∼2060 cm -1 ) were observed, indicating that L binds Ln III through its oxygen atoms of the sulfoxide groups and thiocyanate binds the metal ions with its nitrogen atom . Elemental analyses revealed the components of 1 and 2 to be Ln 2 L 5 (NCS) 6 .…”
