Syntheses, Crystal Structures, and Weak Interactions of Two 4-Substituted Benzyl Triphenylphosphonium Salts Containing Tetrachloromanganate(II) Anion

Two new tetrachloromanganate(II) salts, [4FBzTPP](2)[MnCl4] (1) and [4ClBzTPP](2)[MnCl4]2H(2)O (2) ([4FBzTPP](+) = 1-(4-fluorobenzyl)triphenylphosphonium; [4ClBzTPP](+) = 1-(4-chlorobenzyl)triphenylphosphonium), have been prepared and characterized by elemental analyses, UV-Vis, IR, ESI-MS, molar conductivity and single-crystal X-ray diffraction. The single-crystal structure analysis shows that compound 1 crystallizes in the monoclinic space group P2(1)/c, while 2 is triclinic P-1. Both 1 and 2 comprise one [MnCl4](2-) anion and two cations, and the [MnCl4](2-) anion exhibits distorted tetrahedral coordination geometry. The CHCl, CH hydrogen bonds and stacking interactions in 1 and the CHCl, OHCl hydrogen bonds in 2 result in the forming of a 3D network structure in the solids.
