The cluster structure, thermochemical behavior, and some mechanisms of thermal decomposition of the crystalline products in the isodimorphic substitution series Cu x Ni(1−x ) NTP (x = 0 … 1) have been studied by simultaneous the thermal gravimetric analysis and differential thermal analysis (TGA/DTA) and X-ray photoelectron spectroscopy (XPS). The complexes NiNTP and Cu1/8 Ni7/8 NTP with a monoclinic crystal structure are the most thermo-stable and characterized by one-step decomposition at 400–440 °C with the formation of metal phosphides and phosphates. The complexes Cu3/8 Ni5/8 NTP–Cu3/4 Ni1/4 NTP with the triclinic crystal lattice and the trigonal-bipyramidal coordination of metal atoms decompose in two steps. Firstly, the formation of a heteroligand complex with imino-bis-methylenephosphonic and methylphosphonic acids takes place at 245 °C. Secondly, the complex decomposes at 270–380 °C. The monometallic complex CuNTP decomposes almost completely at 280–300 °C.
