“…In conclusion, compound 2 shows an advantageous decomposition behavior in solution as compared to 1 . The energetic driving force for the decomposition of the precursors is formation of the amino nitrate complexes, which are unstable under heat treatment and tend to decompose vigorously [57] . These are not existent with iron as cation, which is why urea still remains intact to a large extent after decomposition of 1 .…”

“…The energetic driving force for the decomposition of the precursors is formation of the amino nitrate complexes, which are unstable under heat treatment and tend to decompose vigorously. [57] These are not existent with iron as cation, which is why urea still remains intact to a large extent after decomposition of 1. Another positive aspect of the copper coated pigments is that only minor particle agglomeration can be observed during the process (S4).…”

Aluminum pigments were coated with Fe2O3 and CuO by solution‐based thermal decomposition of the urea nitrate compounds hexakisureairon(III)nitrate and tetrakisureacopper(II)nitrate. The deposition process was optimized to obtain homogeneously coated aluminum pigments. The growth of the surface coatings was controlled by investigation with scanning electron microscopy, energy dispersive X‐ray spectroscopy and static light scattering as well as infrared, X‐ray diffraction and thermogravimetric analysis. The iron precursor showed an incomplete decomposition in solution, incorporating traces of urea molecules inside the coatings while the copper precursor showed complete dissociation accompanied by in situ formation of amine complexes. The amount of organic residues resulting from ligand fragments in the final oxide coatings could be reduced to 22 % for the iron oxide and 12 % for the copper oxide by further temperature treatment in solution (259 °C). Colorimetric investigations of the obtained pigments revealed an excellent hiding power, outperforming the pigments used in current state‐of‐the‐art formulations.

[Cu(NH3)2](NO3)2 (I) and [Cu(NH3](NO3)2 (II) were synthesized by interaction of molten NH4NO3 with [Cu(NH3)4](NO3)2 and Cu(NO3)2 · 3 H2O, respectively, at 180 to 195°C for 24 hr. According to X‐Ray single crystal analysis, I is orthorhombic (sp. gr. Pbca) with a = 5.678(1), b = 9.765(2), c = 11.596(2) Å, Z = 4, R = 0.060; II is monoclinic (sp. gr. P21/c) with a = 6.670(1), b = 8.658(2), c = 9.661(2) Å, β = 101.78(2)°, Z = 4, R = 0.027. In both structures, the nearest coordination environment of Cu is a slightly distorted square formed by N (from NH3) and O atoms (from NO3 groups). The structure of I consists of centrosymmetrical [Cu(NH3)2](NO3)2 molecules linked by hydrogen bonds. The CuN and CuO distances are 1.98 and 2.01 Å, respectively. In II, the CuN distance is 1.95 Å, the CuO distances are 1.96, 2.02, and 2.03 Å. The [CuO3NH3] squares are connected by NO3 bridges into zigzag chains, which are linked into layers by longer CuO interactions (2.31 Å). Obviously, the layers are additionally strengthened and held together by hydrogen bonds.
