A dihydroxo-bridged dichromium(III) complex, [Cr2(μ-OH)2(pmida)2] · 4H2O (pmida = N-(2-pyridylmethyl)iminodiacetate), has been prepared and characterized structurally and magnetically. The complex consists of a three-dimensional network in which [Cr2(μ-OH)2(pmida)2] units are alternatively linked by hexacyclic hydrogen-bonded rings adopting the chair conformation. The magnetic susceptibility measured over the range 3–300 K shows there is the antiferromagnetic interaction between the two chromium(III) ions. Based on the Hamiltonian written as H^=-2JS1S2, best fitting for the experimental data leads to J = −13.0 cm−1.
