Abstract
In the title complex, [PtI2(C12H8N2)], the Pt2+ ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the chelating 1,10-phenanthroline ligand and two iodide ions. The nearly planar molecules, with a maximum deviation of 0.170 (3) Å from the least-squares plane, are stacked in columns along the c axis with a Pt⋯Pt distance of 4.8510 (6) Å. In the column, π–π interactions between adjacent six-membered rings are present, the shortest centroid–centroid distance being 3.703 (5) Å.
Highlights
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
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
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
Summary
R factor = 0.033; wR factor = 0.084; data-to-parameter ratio = 14.8.
