“…Data collection: APEX2 (Bruker, 2006); cell refinement: SAINT (Bruker, 2006); data reduction: SAINT; program(s) used to solve structure: SIR2002 (Burla et al, 2003); program(s) used to refine structure: SHELXL97 (Sheldrick, 2008); molecular graphics: ORTEP-3 for Windows (Farrugia, 2012); software used to prepare material for publication: WinGX (Farrugia, 2012), Mercury (Macrae et al, 2006) and POVRay (Persistence of Vision Team, 2004 Research on supramolecular compounds has become popular because of their potential applications in areas such as gas storage (Rowsell & Yaghi, 2005), selective absorption (Dong et al, 2007), catalysis (Wu & Lin, 2007), magnetics (Zhao et al, 2003;Neville et al, 2008) and optics (Huang et al, 2007). P-Ligands are important structural motifs in organic syntheses, coordination chemistry and also in various catalytically active compounds, the tetraphenylphosphonium ion have been widely used in supramolecular chemistry and numerous coordination polymers with versatile structures and potential properties have been reported (Zacharie et al, 1985;Schlueter & Geiser, 2007). Thus, we report here the synthesis of title compound [L 2 .CoCl 4 ], were L is tetraphenylphosphonium and its crystal structure.…”
