The crystal structures of pyridinium manganese(II) chloride monohydrate (PMC) and quinolinium manganese(II) chloride monohydrate (QMC) both contain bi-bridged linear chains. These chains are hydrogen bonded together to form a two-dimensional network. The magnetic susceptibility of QMC is characteristic of a weak antiferromagnet with a maximum in the susceptibility at 2.0 /sup 0/K. Analysis of the data in terms of a 1-d Heisenberg linear chain gives an intrachain exchange constant of J/k=-0.36 /sup 0/K. However, the best model includes significant interchain interactions. Thus, both the structural features and magnetic susceptibility indicate that QMC is a perturbed one-diminsional system. This conclusion is supported by previously reported magnetic susceptibility and ESR data for PMC.
