Summary
Nicotinoyl hydrazide, L, complexes of the MLCl2 · n EtOH type [M = manganese(II), iron(ll), cobalt(II), nickel(II) and copper(II); n = 0 or 1], WL2) (NO3)2 [M = cobalt(II) and nickel(II)] and mixed metal complexes such as HgCo2 L2 Cl6 and (NiL2)HgI4 have been prepared and their nature and structure studied by molar conductance, magnetic susceptibility, electronic, e.s.r. and i.r. spectral measurements. Octahedral structures have been proposed for all the complexes except MnLCl2, CoLCl2 and HgCo2 L2 C16 for which tetrahedral geometry is suggested.
