Two non-linear azide containing heteronuclear complexes: crystal structure and thermal decomposition

Bis-N,N'(salicylidene)-2,2'-dimethyl-1,3-propanediamine (LDMH2) has a high tendency to form polynuclear complexes. Two trinuclear complexes were obtained using this ligand and azide ions; (CuLDM)(2) center dot A Mn(N-3)(2) center dot A (DMF)(2), [(C19H20N2O2Cu)(2) center dot A Mn(N-3)(2) center dot A (C3H7NO)(2)] and (CuLDM)(2) center dot A Cd(N-3)(2) center dot A (DMF)(2), [(C19H20N2O2Cu)(2) center dot A Cd(N-3)(2) center dot A (C3H7NO)(2)]. The structures were identified with X-ray methods. TG and DSC methods were also employed to these complexes. Studies showed the (CuLDM)(2) center dot A Mn(N-3)(2) center dot A (DMF)(2) and (CuLDM)(2) center dot A Cd(N-3)(2) center dot A (DMF)(2) to be non-linear. Also mu-bridges were not encountered for the azide ions but were seen to form b...
