The molecular and crystal structure of, cobalt(II) complex prepared by the reaction of 1,3,5-triphenylformazan with cobalt dichloride, 2,3,5-triphenyltetrazolium dichloro(1,3,5-triphenylformazanato)cobaltate(II), has been determined by means of X-ray diffraction. The complex crystallized in a triclinic space group P\overline 1, with Mr = 728.55, a = 10.214 (3), b = 18.208 (7), c = 9.985 (2) Å, \alpha = 96.44 (3), \beta = 107.92 (2), \gamma = 81.79 (3)°, Z = 2, Dx = 1.387 Mg m-3, \mu = 0.683 mm-1, F(000) = 750, R = 0.041, wR = 0.040 and S = 1.40. The complex is composed of a pair of ions, the 2,3,5-triphenyltetrazolium cation and the dichloro(1,3,5-triphenylformazanato)cobaltate(II) anion. The cobalt(II) ion is tetrahedrally coordinated by two N atoms and two chloride ions. One of the chloride ions of the anion has electrostatic intermolecular contacts with the tetrazolium ring of the cation. The conductivity of the complex in nitromethane solution showed complete dissociation of a pair of ions to separate ions.
