Abstract

Two flexible `polytopic' ligands take part in self assembly reactions with Ni(II) salts to produce helical structures, with `incomplete' metal ion coordination, and the occupancy of empty coordination pockets by a water molecule and a putative fluoride ion. [Ni3(pd2am-H)3(H2O)](NO3)3·2H2O 1 consists of a localized Ni2(N–N)3 dinuclear centre with three N–N single bond bridges, and a distant mono-nuclear Ni(II) centre, within the same molecular ion, and [Ni2(2pzoap)3F](BF4)3·8.5H2O 2 has a dinuclear stucture with two well separated octahedral Ni(II) sites. In both cases a single entity (H2O 1, F−2) occupies a potential coordination pocket. Antiferromagnetic coupling is observed between the adjacent Ni(II) centres in 1, associated with the N–N bridging interactions, but the distant metal centres in 2 are uncoupled.
