Distorted Octahedral

AbstractComplexes of arylidene salicyloyl- and benzoyl-hydrazones with the 3d metal ions, Cr(III), Mn(II), Fe(III), Co(II), Ni(II) and Cu(II), have been prepared using 2:1 ligand to metal ion ratio. Characterization of the isolated solids was accomplished by IR and electronic spectra, elemental analysis, and molar conductivity measurements. It is concluded that the two Schiff bases function as neutral bidentate ligands and the complexes formed assume a distorted octahedral geometry.

Polysaccharide Monooxygenases

A modular one-pot synthesis yielding tetracoordinated-N,N,N,N-copper(I) complexes bearing imine and diimine ligands was developed. Copper aids the condensation of a pyridine or imidazole carbaldehyde with a biphenyl amine and even stabilizes labile ligands. Tetradentate and bidentate ligands were formed, the latter forming homoleptic CuL2 complexes. The identity and purity of the compounds were assessed by NMR, elemental analysis and mass spectrometry. The interconversion of different species in solution was studied by variable temperature NMR. The complexes aim to mimic the histidine copper brace of lytic polysaccharide monooxygenases (LPMOs) and bond lengths obtained from XAS and single crystal XRD for the complexes were compared to reported photoreduced LPMOs.
