Monomeric α-Keggin-type polyoxotungstate-coordinated mono- and di-palladium(II) complexes, i. e., Cs5[α-PW11O39{PdII(Me2ppz)}]·5H2O (Cs-1) (Me2ppz = N,N’-dimethylpiperazine), [(CH3)4N]4H[α-PW11O39{PdII(Me2ppz)}]·8H2O (TMA-1), and Cs2.5H0.5[α-PW11O39{PdII(en)}2]·7H2O (en = ethylenediamine) (Cs-2), were synthesized by 1 : 1 or 1 : 2 stoichiometric reactions of mono-lacunary α-Keggin polyoxotungstate [α-PW11O39]7- with PdCl2(Me2ppz) and PdCl2(en) in aqueous solution Subsequent purification from water afforded these compounds as anal. pure homogeneous yellow precipitates Single-crystal x-ray structural anal. of Cs-1 revealed that a palladium(II) moiety, i. e., [Pd(Me2ppz)]2+, was coordinated to two oxygen atoms in the mono-vacant site of [PW11O39]7- with an asym. configuration, resulting in an overall C1 symmetry. With regard to the crystal structure of Cs-2, two palladium species of the [Pd(en)]2+ type were coordinated to two oxygen atoms in the mono-vacant site with sym. configuration, resulting in an overall Cs symmetry. A unique structural transformation of the mono-lacunary α-Keggin structure of Cs-1 to the di-lacunary γ-Keggin polyoxotungstate Cs7[γ-PW10O36] was observed upon the addition of cesium chloride. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Recommanded Product: Tetramethylammonium chloride).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Recommanded Product: Tetramethylammonium chloride
