Abstract
The anion coordination complex, [Cl⊂Pt(bpt)4]Cl (bpt=N,N′-bis(3-pyridylmethyl)-2-thiourea), was synthesized and studied by X-ray crystal structure analysis, NMR and FAB mass spectra. In the solid state, the Pt(bpt)4 anion receptor adopts a cone conformation to bind the chloride anion through hydrogen bonds and electrostatic interaction in which the four branches of the thiourea ligands bind the chloride anion to form N-H⋯Cl− hydrogen bonds (3.49–3.81 Å). The entraped chloride anion is situated above the Pt(II) center at 3.52 Å. Further second-sphere coordination assemby from the Pt(bpt)4 core with 8 zinc(II) tetraphenylporphyrins (ZnPr) is discussed.
