摘要

The reaction of Ni(mnt)_(2) (mnt = 1,2-dicyano-1,2-ethylenedithiolate) with CuI in THF results in the formation of a Ni(mnt)_(2)Cu_(4)I_(4) unit with an eight-membered Cu_(4)I_(4) crown motif. Coordination polymers with Ni(mnt)_(2)Cu_(4)I_(4) building units, having doubly bridged 1-D chains, were formed with bulky NBu_(4) counterions. To pack the bulky NBu_(4) cations into the crystal structure, no direct interactions between the 1-D chain structures are observed. When the bulky NBu_(4) cations are exchanged for small sodium cations, direct interactions between the 1-D chain structures dominate. A doubly bridged 2-D sheet structure is formed through the bridging of the cyano groups of the Ni(mnt)_(2)Cu_(4)I_(4) units of neighboring 1-D chain structures by sodium atoms. The monomeric [Na_(2)(18-crown-16)]_(2)[Ni(mnt)_(2)Cu_(4)I_(4)] complex is formed when the sodium cations of the 2-D sheet structure are captured by 18-crown-6. The configuration of the coordination polymer or the monomer is controlled through the selection of the appropriate countercation to the Ni(mnt)_(2)Cu_(4)I_(4) building unit. Furthermore, the eight-membered Cu_(4)I_(4) crown motifs in the 2-D sheet structure captures sodium cations. In this regard, we propose that the flexible Cu_(4)I_(4) crown motif is capable of capturing atoms or molecules of various sizes; such a material may act as a useful molecular adsorbent through electrostatic interactions.
