η⁶-Benzene(tricarbonyl)chromium and Cymantrene Assemblies Supported on an Organostannoxane Platform

Abstract

A series of η6-benzene­(tricarbonyl)chromium and cymantrene-containing [cymantrene = cyclopentadienylmanganese­(I) tricarbonyl] assemblies supported on organostannoxane platforms are reported. The reaction of [Cr­(η6-C6H5CO2H)(CO)3] (L1H) with n-Bu2SnCl2 in a 1:1 ratio afforded the tetranuclear derivative [{n-Bu2Sn}2(μ3-O)­(μ-OMe)­(L1)]2 (1) whereas a similar reaction carried out in a 2:1 stoichiometry afforded the mononuclear derivative [n-Bu2Sn­(L1)2] (2). The reaction of (t-Bu2SnO)3 with L1H in toluene in a 1:3 ratio afforded the hydroxide-bridged dimer, [t-Bu2Sn­(μ-OH)­(L1)]2 (3). A 1:2 reaction between [{η6-C6H4(COOH)2 -1,3}­Cr­(CO)3] (L2H2) and Me3SnCl afforded a two-dimensional coordination polymer [{Me3Sn}2(μ4-L2)] n (4). A similar reaction between [{η6-C6H4(COOH)2 -1,4}­Cr­(CO)3] (L3H2) and Me3SnCl in a 1:2 ratio also afforded a two-dimensional coordination polymer [{Me3Sn}2(μ4-L3)] n (5). The reaction of L3H2 with Me3SnCl in the presence of 4,4′-bipyridine afforded a 1D-coordination polymer [(Me3Sn)2(μ-L3)­(μ-4,4′-bipy)] n (6). The reaction of L3H2 with (Ph3Sn)2O (in a 1:1 ratio) gave a dimer [(H2O)­SnPh3(μ-L3)­SnPh3(MeOH)] (7). The 1:1 reaction of [Mn­(η5-C5H4COOH)(CO)3] (L4H) with Me2SnCl2 yielded the tetranuclear derivative [{Me2Sn}2(μ3-O)­(L4)2]2 (8). A similar reaction of [Mn­{η5-C5H4C­(O)­CH2CH2COOH}­(CO)3] (L5H) with Me2SnCl2 in a 1:1 ratio also afforded a tetrameric derivative [{Me2Sn}2(μ3-O)­(μ2-OMe)­(L5)]2 (9). All the compounds were characterized by single crystal X-ray diffraction. Complexes 4 and 5 are planar organometallic 2D-coordination polymers.

Assembly of high-nuclearity Sn26, Sn34-oxo clusters: solvent strategies and inorganic Sn incorporation

“…Many research groups have made great efforts to explore the synthesis and structures of TOCs 12–22. One common way is to use organotin as precursors to react with carboxylate ligands in organic solvents, such as benzene, toluene, and alcohols 23–27. To date, the representative structural types of TOCs are characterized by cubic [ n -BuSn(O)O 2 P( t -Bu) 2 ] 4 ,28 hexameric drum {R′SnO(O 2 CR)} 6 ,29 ladder [(R′Sn(O)O 2 CR) 2 R′Sn(O 2 CR) 3 ] 2 ,30 and Keggin-type alkyltins 31–33.…”

Novel mononuclear and 1D-polymeric derivatives of lanthanides and (η6-benzoic acid)tricarbonylchromium: synthesis, structure and magnetism

“…However, for benchrotrene-based carboxylic acids, there are only few known complexes with alkali and transition metals, and studies of them are mainly focused on structural matters. 14, 15 The study 15 16 Before use in the synthesis, it was dried in a vacuum desiccator. All experiments with the reaction mixtures were carried out in foil-wrapped vessels to prevent photolysis.…”

Imparting Superhydrophobicity to Porphyrinic Coordination Frameworks Using Organotin

“…[26][27][28] Tin has also been used to fabricate MOFs, but only a few examples have been reported to date, most of which are pore-free structures. [29][30][31][32][33][34][35][36][37] As opposed to the introduction of hydrophobic linkers or via PSM by fluoroalkyl chains or other hydrophobic groups on the metal-oxo nodes, theoretically, organotin species could be introduced directly into the SBUs of MOFs to improve the environment of their inner cavities.…”
