Synthesis and Characterization of Hg^II/Se/Cu^I Multinuclear Compounds from Mercury(II) Bis(p‐aminobenzeneselenolate) – Hg(SeC₆H₄NH₂‐p)₂

Abstract

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(SeC 6 H 4 NH 2 ) 2 ] 2 ·diox (1·diox) and its copper(I) derivatives: HgCu 2 X 2 (SeC 6 H 4 NH 2 ) 2 (PPh 3 ) 4 ·4diox [X = Br (2·4diox) and I 544 (3·4diox)]. The compounds 1 and 2, 3 can be considered as the starting material and intermediates, respectively, for the synthesis of ternary Hg II /Se/Cu I nanoclusters. We also provide IR and NMR spectroscopic data and evaluate the optical features of these compounds by difuse reflectance UV/Vis spectroscopy.
