Structural variability and thermally-induced mesomorphisms in complexes of copper(II) with 4-halobenzoates, 2,2'-bipyridine and 4,4'-bis(dodecyl)-2,2'-bipyridine

[Cu2(4-XC6H4COO)4(C2H5OH)2] (X = F, Br) reacted with 2,2′-bipyridine (bpy) to form mononuclear complexes [Cu(4-FC6H4COO)2 (bpy)(H2O)] (1) and [Cu(4-BrC6H4COO)2(bpy)(H2O)]·H2O (2), respectively. The...
