摘要：

The radical anion salt {cryptand[2.2.2](K+)}(6){trans-indigo}(7)5.5C(6)H(4)Cl(2) (1) with a non-integer negative charge on indigo (-0.86 per molecule on average) was obtained. The salt manifests an effective magnetic moment of 1.59 (B) at 300 K and strong enough antiferromagnetic coupling of spins to be mediated by intermolecular hydrogen bonds.
