abstract The synthesis, structure and magnetic properties of a novel Co(II) 1D coordination polymer, [Co(L)(mu(1.5)-dca)(ClO4)(2)center dot MeOH](n) (1) are described. Compound I contains two independent cationic Co (II) chains (CoA and CoB) which are parallel to the c direction and present short pi-pi and C-H center dot center dot center dot pi interactions with two neighbouring chains along the b direction, giving rise to alternating layers of chains A and B in the be plane. Variable-temperature magnetic susceptibility measurements shows a weak antiferromagnetic coupling among the adjacent cobalt(II) centres mediated through mu(1.5)-dca(-) bridge. (C) 2017 Elsevier B.V.
