Compounds of the general formula (CH3NH3)n-1(CH3C6H4CH2NH3)2PbnX3n+1, where X = I, Br, Cl and n= 1,2, 3,..., were prepared and characterized analytically and spectroscopically. Moreover, (CH3C6H4CH2NH3)2PbX4 and (CH3NH3C6H4CH2NH3)2Pb2I7 were characterized by X-ray crystal structure analysis. Their optical absorption and photoluminescence spectra exhibit excitonic bands, even at room temperature.
