摘要

Reactions of [Et4N](2)[MoS4(CuCN)(2)] center dot H2O with bis-(4-pyridyl)propane (bpp) and [Cu(MeCN)(4)][ClO4] in aniline produced [MoS4CU4(bpp)(2)(CN)(2)]center dot 1.5(aniline) (1a). 1a consists of a new three-dimensional [MoS4CU4]-supported open coordination polymer which has a relatively large channel with a volume of ca. 618 angstrom(3) per unit cell. 1a underwent a two-step host-guest process in which the aniline molecules residing in its channels could be partly exchanged with MeCN molecules in 3d and then completely with dimethylformamide molecules in a month, forming {[MOS4Cu4(bpp)(2)(CN)(2)]center dot(aniline)center dot(MeCN)}(n) (1b) and {[MOS4Cu4(bpp)(2)(CN)(2)]center dot(DMF)center dot(MeCN)}(n) (1c), respectively.
