Crystals of 11b (with an equivalent of In) and 11c were obtained from InCl or thermolysis of [In(Cl)(L)N(SiMe3)(C6H3Pri2-2,6)}] (9) prepared in situ from 6 and Li[N(SiMe3)(C6H3Pri2-2,6)] in Et2O}, respectively. Compound 12 was obtained from a thf solution of 11a and sulfur. X-Ray data for crystalline 1–6, 8, 11a, 11b, 11c, 12 and 14 are presented. The

beta-Aminovinylimines containing bulky substituents at the donor nitrogen atoms and copper(II) chelates based on them were synthesized. The compounds were studied by single crystal and powder X-ray diffraction, EXAFS, NMR, EPR, and UV/Vis spectroscopy, and magnetochemistry. The complexes with halide bridges exhibit a ferromagnetic type of spin-spin interaction. The metal chelate containing a phenyl substituent in the gamma-position of the aminovinylimino ligand absorbs atmospheric oxygen in a methylene dichloride solution, which gives rise to a dimer with oxygen bridges exhibiting an anti ferromagnetic type of spin-spin interaction.
Synthesis, crystal structures and spectroscopic properties of copper(I) complexes containing β-dialdiminato supporting ligands
Two mononuclear neutral copper(I) complexes, Cu(L-1)PPh3 (1), Cu(L-2)(PPh3)(2) (2) ([L-1](-) = [N((C6H3Pr2)-Pr-i-2,6)C(H)}(2)CPh](-); [L-2](-) = [N(C6H5)C(H)}(2)CPh](-)) have been synthesized and structurally characterized by X-ray crystallography. In complex 1, the copper(I) atom is in a distorted three-coordinate trigonal planar environment, whereas in complex 2 with the less sterically hindered beta-dialdiminato ligand, the copper(I) atom is the centre of a four-coordinate distorted tetrahedron. At room temperature complexes 1 and 2 in a film of PMMA exhibit green emission at 543 and 549 nm with lifetimes of 5.28 and 5.32 ns, respectively. (c) 2007 Elsevier B.V. All rights reserved.
