“…K 2 Ni(SO 4 ) 2 ·6H 2 O (KNSH) crystal was reported to have a dehydration temperature of 97 • C in 1998, by Northrop Grumman Company [8]. Besides, a number of other crystals were reported as a follow-up, such as Cs 2 Ni(SO 4 [14]. In 2014, guanidine carbonate-doped NSH crystal, whose dehydration temperature was close to 100 • C, had been investigated by Silambarasan et al [15].…”

Four coordinated complexes Mn x Ni (1−x) (C 2 H 6 N 2 O) 6 SO 4 (x=0, 0.33, 0.75, 0.90) were synthesized and characterized. Single-crystal X-ray analysis revealed that the complexes belong to the trigonal crystal family, R-3c space group. Spiral and terraced nucleus growth modes were observed by atomic force microscopy (AFM) in the crystals. Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) measurements showed their excellent thermostability until 200 • C. UV-vis spectra revealed that the transmission peaks of these crystals have a slight bathochromic shift compared to nickel sulfate hexahydrate (NSH), and the transmittance in the UV range increased as the proportion of Mn 2+ increased. With their photophysical properties remaining similar, the much higher heat endurance is rendering these crystals better suitable for UV light filter (ULF) applications.
