Two new salts containing tetrachlorocobaltate(II) anion, [4FBz TPP] 2 [CoCl 4 ](1) and [4ClBzTPP] 2 [CoCl 4 ]·3H 2 O(2) ([4FBzTPP] + = 1-(4'-flurobenzyl)triphenylphosphonium; [4ClBzTPP] + = 1-(4'-chlorobenzyl)triphenylphosphonium), have been prepared and characterized by elemental analysis, IR, UV-Vis, ESI-MS, molar conductivity, and single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system with space group P2 1 /c, whereas 2 crystallizes in the triclinic system with space group P-1. The [CoCl 4 ] 2-anion in two salts exhibits a distorted tetrahedral coordination geometry. The C H···Cl, O H···Cl, and O H···Ohydrogen bonds, p···π and π ···π interactions, or O···O and Cl···O in 1 and 2 consolidate the crystal packing and give further rise to a 3D network structure.
