Abstract

The communication reports the synthesis, characterization, and magnetic behavior of a novel μ₄-carbonato supported and imidazole capped ligated nickel cage [Ni₈(μ-H₂bpmp)₄(μ₄-CO₃)₄(ImH)₈](NO₃)₄·2H₂O (1) through self-assembly of ligand bound ferromagnetic Ni₂ building blocks. Structural analysis indicates newer geometrical features for the coordination cage formation and dominant interdimer antiferromagnetic coupling resulting in a diamagnetic ground state.
