摘要

A three-dimensional copper(II) coordination polymer (CP), {Cu(L-F)(N_3)}_n (1), was synthesized by reacting Cu(NO_3)_2 with 5-fluoronicotinic acid (HL-F) and NaN_3 in a water medium. Complex (1) shows a 3D network, in which the 1D [Cu_2(COO)N_3]_n chains are interconnected via L-F ligands. By immersing (1) into different short-chain alcohols (CH_3OH, C_2H_5OH and HOC_2H_4OH), three different CPs were isolated, including {Cu_3(L-F)_4(N_3)_2(CH_3OH)_2}_n (2), {Cu_3- (L-F)_4(N_3)_2(C_2H_5OH)_2}_n (3) and {Cu_(2.5)(L-F)_3(N_3)_2(HOC_2H_4OH)_(0.5)}_n (4). CPs (2) and (3) display a similar structure, in which trinuclear subunit [Cu_3(COO)_2(N_3)_2(solvent)_2] is generated. Furthermore, such entities are interconnected via L-F ligands to give rise to a 3D network. As for (4), there are trinuclear [Cu_3(COO)_2(N_3)_2] and binuclear [Cu_2(COO)N_3] units, which are interconnected by L-F ligands to generate a 3D network. Notably, in (2) and (3), the coordination modes of CH_3OH and C_2H_5OH solvents are monodentate; whereas for (4), the HOC_2H_4OH solvent adopts a bridging mode to link two Cu atoms. Of further interest, these processes are solvent-mediated structural transformations, with obvious colour changes in the crystals. Structural changes and mechanisms of transformation are discussed in detail.
