(PPh4)2[CuCl(NO3)3] · CH2Cl2 is formed when ozone reacts with (PPh4)2[Cu2(N3)6] in dichloromethane. Its crystal structure was determined by X-ray diffraction. Crystal data: a = 1113(1), b = 1156(1), c = 1965(2) pm , α = 101.02(1), β = 93.74(1), γ = 104.05(2)° at 130 K, space group P1̄, Z = 2, R = 0.057 for 3951 observed reflexions. The structure contains CH2Cl2 molecules and PPh4+ and [CuCl(NO3)3]2- ions, with copper having coordination number 5. One nitrate ligand acts as a bidentate chelating unit, and the other two as monodentate ligands.

A new homo-trinuclear Ni(II) half-salamo-based complex [Ni3(L)2(μ-OAc)2(OAc)2(CH3OH)2]·2CH3OH was synthesized via the reaction of a tridentate ligand HL (2-[O-(1-ethyloxyamide)]oxime-4-bromophenol) and Ni(OAc)2·4H2O, and characterized using elemental analyses, IR spectra, UV-Vis absorption spectra, X-ray crystallography, and Hirshfeld analysis. Interestingly, single-crystal X-ray analysis showed that the two acetate molecules were bonded simultaneously with the Ni(II) atoms by mono-dentate chelating and bidentate bridging coordination modes, respectively, and the resulting hexa-coordinate geometries were ultimately formed. Furthermore, the Hirshfeld analysis of the complex was studied. Compared with HL, the complex fluorescence intensity was significantly lowered, indicating that the Ni(II) ions have fluorescence quenching characteristics.
