A novel linear-chain material showing sandwiched stacking via alternative Pt(II)⋯Pt(II) or Pt(II)⋯S and π⋯π interactions

A novel linear-chain material, [Pt(8-QNS)2][Pt(terpy)Cl]2(ClO4)2 (8-QNS=8-quinolinethiolate; terpy=2,2′:6′,2″-terpyridine), has been serendipitously isolated and characterized by a crystallographic study. The title compound composed of alternative cationic [Pt(terpy)Cl]+ pairs and [Pt(8-QNS)2] moieties is formed by an interesting rearrangement process, and it shows sandwiched stacking via alternative Pt(II)⋯Pt(II) or Pt(II)⋯S and π⋯π interactions.
