In this paper we explore an amino functionalized selenolate unit for the synthesis of new multinuclear compounds with promising interesting properties and potential precursors of semiconductors. We present for the first time the X‐ray crystallographic structure of [Hg(SeC6H4NH2)2]2·diox (1·diox) and its copper(I) derivatives: HgCu2X2(SeC6H4NH2)2(PPh3)4·4diox [X = Br (2·4diox) and I (3·4diox)]. The compounds 1 and 2, 3 can be considered as the starting material and intermediates, respectively, for the synthesis of ternary HgII/Se/CuI nanoclusters. We also provide IR and NMR spectroscopic data and evaluate the optical features of these compounds by difuse reflectance UV/Vis spectroscopy. [ABSTRACT FROM AUTHOR]

This paper describes the synthesis and structural characterization of two new one-dimensional coordination polymers involving 1,3-bis(4-pyridyl)propane ligand named {(μ-NCS)2[Cu(bpp)] ·dmf} n ( 1) and {[Cu(mebpy)(bpp)(dmso)](ClO4)2 ·dmso} n ( 2) (bpp = 1,3-bis(4-pyridyl)propane and mebpy = 4,4'-dimethyl-2,2'-bipyridine). These compounds were characterized by means of elemental analysis, thermal analysis (TG/DTA), vibrational spectroscopy (IR and Raman) and had their structures determined by single-crystal X-ray diffraction analysis. Compound 1 consists of CuN4 coordination spheres with bpp ligands in the unusual GG conformation coordinated in bridges between CuII centers to form a wavelike 1-D coordination polymer. On the other hand, in compound 2 the bpp ligand adopts the TT conformation in bridging mode extending the 1D cationic polymeric chain. [ABSTRACT FROM AUTHOR]
