Experimental values of the temperature and percentage of mass loss observed in each step of the TG-DTG curves in an inert atmosphere.

Compound	Temperature °C (%) mass loss		Products
	First step	Second step	First step; Second step
1	50–200/10.8 (calcd. 10.5%)	220–250/62.1 (calcd. 63.4%)	[Cu(1)(NO3)]NO3 Cu(NO3)2
2	50–200/3.89 (calcd. 3.52%)	230–270/62.7 (calcd. 63.3%)	[Cu(2)(NO3)]NO3 Cu(NO3)2
3	30–120/6.11 (calcd. 6.59%)	250–500/50.8 (calcd. 49.7%)	[Ni(1)(NO3)]NO3 Ni(NO3)3
4	280–320/47.7 (calcd. 49.9%)	—	Ni(NO3)3
