Synthesis and spectroscopic properties of large single-crystals of Pb(II), Hg(II) and Sr(II) methanesulfonato 1D coordination polymers

Abstract

Three new 1D coordination polymers, [Pb 2 (CH 3 SO 3 ) 4 (H 2 O) 2 ] n , [Hg(CH 3 SO 3 ) 2 (H 2 O) 2 ] n and [Sr(CH 3 SO 3 ) 2 (H 2 O)] n , were synthesized as large single crystals. The crystals were analyzed and characterized by the means of X-ray analysis, IR and NMR spectroscopy, elemental analysis and solid state UV-Vis spectroscopy. The formation of 1D polymeric chains in the crystal structures of the title compounds is affected by the various bonding modes of the bridging methanesulfonate groups. The studied compounds showed no decomposition in the air.

Metal Methanesulfonates with Mixed Anionic Groups with Large Band Gaps and Enhanced Birefringence

“…Metal methanesulfonates initially attracted attention for their catalytic properties in various organic synthesis reactions. , A number of the compounds have been reported, encompassing diverse metals (M), including alkali metals (M = Li, Na, K, Rb, Cs), , alkaline-earth metals (M = Mg, Ca, Sr, Ba), , transition metals (M = Mn, Cu, Zn, Ag, Cd etc. ), , and post-transition metals (M = Ge, Sn, Pb, Hg). − There are only three reported bimetallic methanesulfonates, MAu­(CH 3 SO 3 ) 4 (M = Li, Na, Rb) . To the best of our knowledge, metal methanesulfonates with mixed anions or anionic groups have not been reported.…”

Synthesis and Characterization of the Germanium Sulfonate Ge(CH3SO3)2 – a 3D Coordination Network Solid

“…In such compounds the CH 3 SO 3 – group most commonly acts as bridging ligand and exhibits multidentate coordination, which results in the formation of coordination network solids 10,11. Three‐dimensional (3D) networks have been reported for [ n Bu 2 Sn{OP(O)(OH)Ph}(CH 3 SO 3 )] n ,12 two‐dimensional (2D) structures for ( M O 2 )(CH 3 SO 3 ) 2 ( M = Mo, U) 4 and [(Et 2 Sn) 6 (O 3 P t Bu) 4 (CH 3 SO 3 ) 4 · 2H 2 O] n ,13 and one‐dimensional (1D) coordination polymers for [Sr(CH 3 SO 3 ) 2 (H 2 O)] n ,14 [AgL 1–Me (CH 3 SO 3 )] n [L 1–Me = bis(methylthio)methane],15 Pd(CH 3 SO 3 ) 2 5 and (ReO 3 ) (CH 3 SO 3 ) 4. Recently, the syntheses and crystal structures of the low valent group 14 methanesulfonates Pb(CH 3 SO 3 ) 2 and Sn(CH 3 SO 3 ) 2 have been studied by Gagelmann et al16,17 With regard to the title compound Ge(CH 3 SO 3 ) 2 , both need to be addressed in more detail.…”

“…Single crystals of the anhydrous sulfonates M (CH 3 SO 3 ) 2 ( M = Pb II , Sn II ) have been reported to crystallize in the polar space group Pca 2 1 for Pb II and in the chiral space group P 4 3 2 1 2 for Sn II , respectively. Recently, also hydrated [Pb 2 (CH 3 SO 3 ) 4 (H 2 O) 2 ] n was reported, which was obtained upon reaction of PbCO 3 with an aqueous solution of methanesulfonic acid and crystallized in the space group P $\bar{1}$ 14…”
