Title compds. I (X = 2-, 3-, 4-CH2OH) were prepd. and characterized by x-ray crystallog. The magnetic susceptibility was detd. by temp.-dependent SQUID measurements. I (X = 2- and 4-CH2OH) display a paramagnetic susceptibility which follows the Curie-Weiss law. Weak ferromagnetic interactions can be recognized at very low temp. I (X = 3-CH2OH) shows temp.-dependent antiferromagnetic behavior which can be fitted perfectly with the Heisenberg linear-chain theory with an intrachain exchange interaction of -18.43 cm-1.
