Abstract
Trans-dichlorobis(ethylenediamine) cobalt(III) terafluoroborate was synthesised and detailed packing analysis was undertaken to delineate the topological complimentarity of [trans-Co(en)2Cl2]+ and BF4− ions by second sphere coordination. The complex was completely characterised by elemental analyses, solubility product measurement and spectroscopic studies (IR, UV–Vis, multinuclear NMR). In the crystal lattice, discrete ions [trans-Co(en)2Cl2]+ and BF4− are arranged in A–B–A–B pattern (in both a and c directions of the lattice) forming columns of anions and cations. Crystal lattice is stabilized by electrostatic forces of attraction and hydrogen bonding interactions, i.e. N–H⋯F− and N–H⋯Cl involving second sphere coordination. It appears that the topological features of [trans-Co(en)2Cl2]+ are conducive for generating second sphere interactions. This strategy may be used as a viable method for the capture of other fluoroanions.
