Crystal and Electronic Structures of Quasi-One-Dimensional Halogen-Bridged Binuclear Platinum Complexes, {(C n H 2n+1 ) 2 NH 2 } 4 [Pt 2 (pop) 4 I] (n=2-6)

The crystal structures of {(C n H 2n+1 ) 2 NH 2 } 4 [Pt 2 (pop) 4 I] (pop=O(PO 2 H) 2 2− , n=2-6) have been determined. Judging from the results of the X-ray structural analyses and Raman spectra, 1-D electronic structures of these compounds are consider to be …Pt 2+ -Pt 3+ -X …Pt 2+ -Pt 3+ -X… charge-polarized states.
