• From magnetic susceptibility and ESR measurements, it has been confirmed that polybis(μ-(2-picoline <I>N</I>-oxide)-chlorocopper(II)di-μ-chloro)diaquocopper, Cu<SUB>3</SUB>Cl<SUB>6</SUB>(C<SUB>6</SUB>H<SUB>7</SUB>NO)<SUB>2</SUB>·2H<SUB>2</SUB>O, consists of alternating linear chains with diamagnetic Cu<SUB>2</SUB>Cl<SUB>4</SUB>(C<SUB>6</SUB>H<SUB>7</SUB>NO)<SUB>2</SUB> units and paramagnetic CuCl<SUB>2</SUB>·2H<SUB>2</SUB>O units joined by long Cu–Cl bonds. The two copper ions in the Cu<SUB>2</SUB>Cl<SUB>4</SUB>(C<SUB>6</SUB>H<SUB>7</SUB>NO)<SUB>2</SUB> unit are coupled together very strongly by antiferromagnetic exchange interaction and occupy almost entirely the diamagnetic singlet state below room temperature. This interpretation is appropriately supported by the observation of a half-field resonance near 1600 Oe in the ESR spectrum of the powdered sample. On the other hand, the copper ion in the CuCl<SUB>2</SUB>·2H<SUB>2</SUB>O unit isolated magnetically can account for the ESR spectrum due to <I>ΔM</I>=±1 transition and magnetic susceptibility, following the Curie law. The magnetic susceptibility of the dehydrate compound, Cu<SUB>3</SUB>Cl<SUB>6</SUB>(C<SUB>6</SUB>H<SUB>7</SUB>NO)<SUB>2</SUB>, has also been measured.
