(2), and Cu2(L3)2(μ1,1-N3)2] (3), where L1, L2, and L3 are the deprotonated forms of 4-bromo-2-(2-methylaminoethylimino)methyl]phenol (HL1), 4-bromo-2-(2-ethylaminoethylimino)methyl]phenol (HL2), and 4-bromo-2-(2-isopropylaminoethylimino)methyl]phenol (HL3), respectively, have been prepared and structurally characterized by single-crystal X-ray diffraction analysis and IR spectra.
The slight differences in the terminal groups of the Schiff bases lead to different bridging modes of the azido groups. |
