A novel fluoride-centered triangular-bridged carboxylate complex, [Ni₂Cr(μ₃-F)(O₂C^tBu)₆(HO₂C^tBu)₃] (1), is reported. Simple postsynthetic substitution of the terminal pivalic acids in 1 with pyridine and 4-methylpyridine led to the isolation of [Ni₂Cr(μ₃-F)(O₂C^tBu)₆(C₅H₅N)₃] (2) and [Ni₂Cr(μ₃-F)(O₂C^tBu)₆((4-CH₃)C₅H₄N)₃] (3). Structural and magnetic characterizations carried out on the series reveal a dominating antiferromagnetic interaction between the nickel and chromium centers leading to an S = ¹/₂ ground state with a very unusual value of g_eff = 2.48.
