The coordination adducts of MnCl2, FeCl3, CoCl2, NiCl2 and CuCl2 with
DMF were isolated and characterized by elemental analysis, magnetic mo
ments, UV-VIS spectroscopy, IR spectroscopy and thermal analysis techn
iques. The shift of the CO stretching vibration to low frequency indic
ated that DMF is bonded through oxygen to the metals. On the basis of
spectral and elemental analysis data, the complexes have dimeric and t
rimeric structures achieved by the chlorine bridges. The complexes do
not have melting points and undergo decomposition after dehydration. T
he decomposition of DMF in the complexes occurs in several stages and
the last stages of decomposition always corresponds to decomposition o
r sublimation of the respective metal chlorides to produce the respect
ive metal. (C) 1997 Elsevier Science B.V.
