Three new coordination polymers [Co(bimb)2(NCS)2]n (1), {[Co(bimb)2(dca)2] ยท CH3CN}n (2) and [Cu(bimb)2(NO3)2]n (3) (bimb = 1,4-bis(imidazol-1-yl)butane, dca = dicyanamide) were synthesized and characterized. In 1, each Co(II) links two Co(II)'s by double bimb ligands and extends to form a one-dimensional chain containing the Co2(bimb)2 22-membered metallocycle. 2 and 3 are two-dimensional (4, 4) networks linked by bimb bridges. The conformations of the bimb ligands in 1, 2 and 3 are analyzed.
