A new 2D dibutyltin coordination polymer with 3,5-dinitrosalicylate and 4,4’-bipyridine ligands

Abstract

A new 2D dibutyltin coordination polymer with 3,5-dinitrosalicylate and 4,4’-bipyridine ligands, [{Bu2Sn(3,5–(NO2)2–2–OC6H2COO)}2(4,4’-bpy)]n (1), has been synthesized and characterized both spectroscopically (IR, 1H, 13C, and 119Sn NMR) and a single-crystal X-ray diffraction analysis. The coordination geometry of tin atom in 1 is a distorted octahedron. 3,5-Dinitrosalicylate as doubly charged anion ligand adopts chelating-bridging mode to coordinate to tin atoms, and 4,4’-bipyridine further bridges the tin atoms to form a 2D herringbone-like network structure containing the 34-membered hexa-nuclear macrocycles.

Approach to Di/Triorganotin(IV) Cations via Hydrolysis of Stannate Salts Bearing Alkanesulfonate Ligands

“…The sheets are arranged in an offset manner with an interlayer Sn–Sn distance of 7.87 Å. While there exist a few reported studies on the organotin polymers with organic N-donor linkers, the structure of 7 represents a unique example of a cationic one-dimensional motif with a C 3 SnN 2 core and sulfonate groups as the counter ions.…”
