1,3-Bis(2-R-tetrazol-5-yl)triazenes MTTH (R = Me) and BTTH (R = 
t
Bu) were found to 
deprotonate upon reaction with copper(II), platinum(II), and palladium(II) chlorides in neutral or 
acidic media to give square planar complexes of general formula MLCl (M = Cu, Pt, Pd; L = 
MTT, BTT), in which 1,3-bis(2-R-tetrazol-5-yl)triazenate ions act as tridentate chelating ligands. 
Products were characterized  by elemental analysis,  UV-vis and IR spectroscopy, thermal and 
X-ray diffraction analyses. The structures of Pd(MTT)Cl (Fig. 1) and Cu(BTT)Cl·(BTTH) 
complexes were established by X-ray analysis. The most remarkable feature of the absorption 
spectra of platinum(II) and palladium(II) 1,3-bis(2-R-tetrazol-5-yl)triazenates are charge-transfer 
bands in the visible spectral region, with a markedly resolved structure even at room temperature 
in solutions (Fig. 2).
