Synthesis, properties, and theoretical studies of new stepwise layered iodoplumbate: [Ni(opd)2(acn)2]n[Pb4I10]n.
A novel 2D layered iodoplumbate, [Ni(opd)(2)(acn)(2)](n)[Pb(4)I(10)](n) (1), yellow-green in color, has been synthesized. The anionic [Pb(4)I(10)(2-)](n) layer is comparable to the hexagonal PbI(2) sheet but in a lower symmetry. Although the intercalated cations contribute negligibly to the electron transition, they induce the reconstruction of the inorganic moiety, which leads to a band-gap blue shift with respect to that of PbI(2).
