One-dimensional antiferromagnetic cycloheptatrienyl molybdenum and tungsten compounds
Abstract
The 17 -electron compounds [M(η-C7H7)LX2](M = Mo, L = MeCN, X = I 1; M = Mo, L = PMe3, X = I 2; M = W, L = MeCN, X = I 3; M = W, L = PMe3, X = I 4; M = W, L = PMe3, X = Br 5) have been prepared. All exhibit antiferromagnetic interactions with temperatures at χmax ranging from 12 to 17 K. The magnetic susceptibility data have been described by one-dimensional magnetic models. The crystal and molecular structures of [Mo(η-C7H7)(MeCN)l2]1 have been determined, and confirm the one-dimensional structure.
