Electronic Supplementary Information Multifunctional cadmium single source precursor for the selective deposition of CdO or CdS films from a solution route

Experimental. Elemental microanalyses were performed in the Analytical Laboratories of the University of Catania. 1H NMR spectra were recorded on a Varian Inova 500 spectrometer. Infrared spectra were recorded on a Perkin Elmer FTIR 1720 spectrometer as nujol mulls between NaCl plates. Thermogravimetric analyses were performed by using a Mettler Toledo TGA/SDTA 851. Weights of the samples were between 10-15 mg (TGA). Analyses were made under prepurified nitrogen using a 5°C/min heating rate. The H NMR spectrum of the Cd(tta)2•tmed adduct shows a singlet at δ = 6.12 ppm, whose integration accounts for the two protons, one for each tta ring. The multiplets at δ = 7.07, δ = 7.47 and δ = 7.60 represents the resonance of the protons of the tiophene ring. In addition, multiplets at δ = 2.51 and δ = 2.63 represent resonances of the six and four protons, respectively, of the tmed methylic and methylenic groups. The C NMR spectrum of the Cd(TTA)2•tmed adduct shows a singlet at δ = 47.06 and a singlet at δ = 56.82, associated with carbons of the methylic and methylenic groups, respectively, of the
