Abstract
Two new tetrachloromanganate(II) salts, [4FBzTPP]2[MnCl4] (1) and [4ClBzTPP]2[MnCl4]·2H2O (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 P21/c, while 2 is triclinic P-1. Both 1 and 2 comprise one [MnCl4]Citation2– anion and two cations, and the [MnCl4]Citation2– anion exhibits distorted tetrahedral coordination geometry. The C‒H···Cl, C‒H···π hydrogen bonds and π···π stacking interactions in 1 and the C‒H···Cl, O‒H···Cl hydrogen bonds in 2 result in the forming of a 3D network structure in the solids.
