Abstract
The preparation, crystal structures and optical absorption spectra of [CH3SC (= NH2)NH2](3)PbI5 1, [CH3SC (=NH2)NH2](4)Pb2Br8 2 and [CH3SC(= NH2)NH2](3)PbCl5. CH3SC (=NH2)NH2Cl 3 are reported. Compounds 1 and 3 consist of deformed PbX6, octahedra, which share opposite corners to f orm quasi-zero-dimensional or one-dimensional infinite chains along th e a-axis. Compound 2 consists of Pb2Br9 units which-are connected with two neighbouring units by non-opposite Br atoms; in this way, infinit e zigzag chains are formed. A blue shift of the excitonic absorption b ands, in comparison to those of systems with higher dimensionality, is observed.
