Aseries of M-M-heterometallic coordination polymers: syntheses structures properties (M=Ni^+2/M^-=Ag^+1, Cd^+2, Zn^+2)

In this paper a series of new mono and heterometallic ni(ii) complexes of the general formula[ni(3-hophdtc)2],[ni(ag(3-hophdtc)2}2], niln(ag(3-hophdtc)2}2], nim(3- hophdtc)4] ,[ni(l)nm(3-hophdtc)4].3-hophdtc=3-hydroxy phenyl dithiocarbamate.when n = 2, l quinoline, 4-picoline, when n= 3, l= ethylenediamine, 1,10 phenanthroline, m=zn^+2,cd^+2. all the isolated complexes have been characterized by atomic absorption, elemental analysis,molar conductivity, infrared, electronic absorption spectra and magnetic measurement.the conductivity measurements proved the non-electrolytic behaviour of all the compounds, suscetptibility measurements and electronic spectra shows a tetrahedral geometry for complexes of the type [ni(3-hophdtc)2],[ni(ag(3-hophdtc)2}2], nim(3- hophdtc)4] and octahedral geometry for complexes of the type niln(ag(3- hophdtc)2}2],[ni(l)nm(3-hophdtc)4].
