Diaqua­bis(1,10-phenanthroline-κ²N,N′)cobalt(II) dihydrogen­phosphate nitrate dihydrate

The structure of the title compound, [Co(C₁₂H₈N₂)₂(H₂O)₂](H₂PO₄)(NO₃)·2H₂O, is built up from layers of complex [Co(C₁₂H₈N₂)₂(H₂O)₂]²⁺ cations and phosphate units parallel to (010), delimiting a-axis tunnels in which the nitrate anions and the water mol­ecules are located. The mol­ecular structure is stabilized by inter­molecular hydrogen bonds and weak π–π stacking inter­actions.

Special details

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.
