资源简介：
Metal-directed assembly of naphthalene-1,4,5,8-tetracarboxylic
acid (NTA) with different transition-metal salts in the presence of
ammonia results in a series of one-dimensional metal–naphthalenediimidato
(M–NDI) coordination polymers with the formulas of {[Ag(NDI)](NH4)}n (P1), [Zn(NDI)(NH3)2]n (P2), [Cd(NDI)(NH3)2]n (P3), [Co(NDI)(NH3)2]n (P4) and [Ni(NDI)(NH3)2]n (P5), respectively.
It is worthwhile to mention that the 1D straight-line NDI–Ag(I)
coordination polymer P1 is formed stepwise from a dinuclear
NDI–Ag(I) intermediate [Ag2(NDI)(NH3)2] (2AgNDI), where ammonia serves as a stabilizing
reagent of Ag(I) ion and a weak base to remove the protons of NDIH2 simultaneously. Furthermore, P1 exhibits semiconducting
properties in the solid state which may originate from its all-parallel-aligned
packing structure (AAAA) which is different from the common ABAB packing
mode for P2–P5 and 2AgNDI. In addition, theoretic computational studies as well as X-ray photoelectron
spectrometer spectra on P1 and 2AgNDI have
also been carried out.
