Two Isostructural Coordination Polymers Showing Diverse Magnetic Behaviors: Weak Coupling (Ni-II) and an Ordered Array of Single-Chain Magnets (Co-II)

Two isomorphic 3-D complexes with the formulas [M-3(TPTA) (OH)(2)(H2O)(4)](n) (M = Ni for 1 and Co for 2; H(4)TPTA = [1,1':4',1 ''-terphenyl]-2',3,3 '',5'-tetracarboxylic acid) have been synthesized and magnetically characterized. Complexes 1 (Ni-II) and 2 (Con) have the same 1-D rod-shaped inorganic SBUs but exhibit significantly different magnetic properties. Complex 2(Co-II) is a 3-D arrangement of a 1-D Co-II single-chain magnet (SCM), while complex 1(Ni-II) exhibits weak coupling.
