The metallic skeleton of 1 is a single stranded wheel (Fig. ). The bridging between each pair of Ni II ions is the same around the entire wheel and consists of one µ-Cl ion (Ni-Cl-Ni, ~82.0-85.1°), and one µ-O atom (Ni-O-Ni, ~102.8-103.2°) and one µ-carboxylate which both derive from the syn, syn, anti-bridging formate (Fig. ). The six-coordinate Ni II ions are all in distorted octahedral geometries with their {NiO3Cl2N} coordination spheres completed by a terminally bonded HL 2 ligand. The latter and the formate ions originate from the in-situ reaction of HL The only exception to this is Ni5, {NiO4Cl2}, in which there resides a disordered MeOH/H2O molecule in place of the HL 2 ligand. The wheel is non-planar with nearest neighbour Ni II ions being above and below the plane running through the middle of the fourteen metal ions, i.e., they form a zigzag/sinusoidal "up-down-up-down" motif as the wheel is circumnavigated (Fig. ). The approximate dimensions of the wheel are, Ni1 Dc magnetic susceptibility (χ) and magnetisation (M) measurements of 1 were taken in the T = 300-1.80 K, B = 0.1 T and T = 2.0-10 K and B = 0.5-9.0 T temperature and field ranges, respectively. These are plotted as the χT product versus T, and M versus B in Fig. . The T = 300 K value of χT = 18.5 cm 3 K mol -1 is equal to the value expected for fourteen non-interacting Ni II ions with g = 2.30. Upon cooling the χT value remains relatively constant, increasing only very slowly to ~24 cm 3 K mol -1 at 50 K before rising sharply to a maximum of ~104 cm 3 K mol -1 at T = 3 K. The value then drops to ~96.3 cm 3 K mol -1 at 2 K. The M vs B data increases rapidly with increasing field, saturating at a value of M = 32.1 µB at T = 2 K and B = 9 T. The susceptibility and magnetisation data are therefore indicative of weak ferromagnetic nearest neighbour exchange and the stabilisation of an S = 14 spin ground state.
