Mixed-Ligand Copper(II) Complexes with the Rigid Bidentate Bis(N-arylimino)acenaphthene Ligand: Synthesis, Spectroscopic-, and X-ray Structural Characterization
AbstractA new Mn(II) complex [Mn2(L)(H2O)3] · (H2O)4.8(1) was synthesizedviathe hydrothermal reaction of MnCl2 · 4H2O withN4,N4′-di(5-isophthalyl)biphenyl-4,4′-dicarboxamide (H4L). Complex1is characterized by single-crystal and powder X-ray diffraction, infrared spectroscopy, and elemental and thermogravimetric analyses.1exhibits a uninodal 5-connected 3Dbnnframework structure with (46.64) topology. The magnetic properties of1were investigated.
The synthesis of the following mixed ligand complexes is reported: [Ni(phdtc)2(dpm)2], [Ni(phdtc)2(dpe)2], [Ni(phdtc)2(dpp)3], [Ni(1-naphdtc)2(dpm)2], [Ni(1-naphdtc)2], and [Ni(1-naphdtc)2(dpp)2], where phdtc = PhNHCSS-, 1-naphdtc = 1-NaPhNHCSS-, dpm = Ph2PCH2PPh2, dpe = Ph2P(CH2)2PPh2, and dpp = Ph2P(CH2)3PPh2. The complexes are characterised by microanalysis, IR and UV-Vis spectra, magnetic measurements, conductivity, X-ray powder diffraction, and thermal analysis. All the mixed ligand complexes are diamagnetic, and thus a square-planar or square-pyramidal (low-spin) structure was proposed for the present complexes.
