摘要：

The complexes [(CH3)(3)NCH2CONH2](2)[M(S-2-o-xyl)(2)], M = Fe (1), Co (2), and [(CH3)(4)N](2)[Co(S-2-o-xyl)(2)]. 1/2C(2)H(5)OH (3) have been characterized by X-ray crystallography and vibrational spectroscopy. Complexes 1 and 2 exhibit linear one-dimensional concatenated hydrogen bonded structures. In complex 2 there is an increase in the average metal-ligand bond length in the hydrogen-bonded form relative to 3, which contains a non-hydrogen bonded congener. (C) 1999 Elsevier Science S.A.
