摘要: Novel lead pseudo polymorphs supported by diselenophosphate (dsep) ligands, [Pb{Se2P(OiPr)2}2]n (1α and 1β), were synthesized structurally characterized. The two structures differed in the binding modes of dsep ligand. Each repeating unit 1α was composed a atom coordinated one chelating mode other bridging–dangling mode. By contrast, ligands 1β adopted bimetallic-biconnective (μ1-S, μ1-S) pattern. observed is first example this for could be successfully utilized as single source precursor (SSP) growing selenide (PbSe) nanostructures with different shapes via solvothermal process. morphologies as-grown PbSe controlled capping agents, poly(vinyl pyrrolidone) (PVP) ethylenediamine, both bind on {200} plane enhance growth rate direction crystals, resulting formation cubes eight-horned rod dendrites, respectively. Raman spectroscopy to investigate phonon vibration behaviour dendrites. All peaks spectra can attributed longitudinal (LO) transverse (TO) optical
