Poly[aqua­(μ-5′-carb­oxy-2,2′-bipyridine-5-carboxyl­ato)dichlorido­rubidium(I)platinum(II)]

In the bimetallic coordination polymer [PtRbCl₂(C₁₂H₇N₂O₄)(H₂O)]_n, the Pt^II atom has a square-planar configuration, with two cis-coordinated N atoms from a 2,2′-bipyridine-5,5′-dicarboxyl­ate ligand and two terminal Cl atoms. The carboxyl­ate groups are further connected to Rb ions, forming two-dimensional sheets, which again are linked together through Rb—Cl bonds, forming a three-dimensional structure. The bimetallic coordination polymer contains Pt^II sites with the same configuration as homogenous Pt-containing metal–organic complexes, which proved to be active species in C—H bond-activation reactions.

ABSTM02_ALERT_3_G  When printed, the submitted absorption T values will be
            replaced by the scaled T values. Since the ratio of scaled T's
            is identical to the ratio of reported T values, the scaling
            does not imply a change to the absorption corrections used in
            the study.

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.
