The Co^II atom in the title salt, (C₁₀H₁₈N)₂[CoCl₄], exists in a tetrahedral coordination geometry. The asymmetric unit has two cations that lie on different special positions of site symmetry m; the anion lies on another special position of site symmetry m.

Experimental top

1-Aminoadamantane (6.05 g, 40 mmol) and salicylaldehyde (5.01 g, 41 mmol) were heated in ethanol (50 ml) for 1 h. The N-salicylidene-1-aminoadamantane that separated was collected in 70% yield, m.p. 366 K. Cobalt dichloride hexahydrate (1 mmol) dissolved in ethanol (10 ml) was reacted with the Schiff base (2 mmol) dissolved in alcohol (5 ml) to give a blue solution. Blue crystals separated from the solution after three weeks.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
