Self‐assembly syntheses and crystal structures of dimeric di‐n‐butyltin phosphates containing eight‐membered Sn₂O₄P₂ inorganic ring

Abstract

Two organotin (IV) derivatives, [Bu2‐ Sn(HO3PO‐i‐Pr)2]2 (1) and [Bu2Sn(HO3POPh)2]2 (2), have been prepared by reactions of di‐n‐butyltin oxide with the phenylphosphoric acid and isopropylphosphoric acid, respectively. Characterization of the complexes 1 and 2 was achieved using elemental analysis, IR, NMR (1H, 13C, 31P, and 119Sn) spectroscopy, and X‐ray crystallography diffraction analysis. The X‐ray data reveal that complexes 1 and 2 are dimers containing eight‐membered Sn2O4P2 inorganic ring. Interestingly, complexes 1 and 2 are further linked into 2D network through intermolecular O … Sn weak contacts and OH … O weak hydrogen‐bonding interactions. © 2010 Wiley Periodicals, Inc.

Two new organotin(IV)-phosphoryl complexes: crystal structure and Hirshfeld surface analysis

“…The Sn centre have been used in preparation of tin complexes, for example compounds with [N] 3 P(O) [11][12][13] [20,21] segments. Moreover, different coordination environments [22,23] and coordination numbers [24,25] at the Sn atom and also coordination modes (monomer [20], dimer [18,26], polymer [27][28][29] and so on [30,31]) and crystal packing diagrams have been found among through the tin-phosphoryl complexes structures deposited in the Cambridge Structural Database (CSD, version 5.35, February 2014 update) [32].…”
