| Abstract: | Reaction of the precursor Ir complex Ir(H)2(PPh3)2(Me2CO)2]PF6 with 3,6-bis(2-pyridyl)tetrazine (bptz) in CH2Cl2 gave a novel dinuclear Ir hydrido complex Ir2(H)4(PPh3)4(bptz)](PF6)2 · 4CH2Cl2. Crystallographic study described an interesting coordination environment having a π-π interaction and 1H NMR study showed unique upfield shifts of pyridyl rings that are likely induced by the ring current effect of neighboring PPh3 ligands. |
