Zinc tri-tert-tuboxysilanethiolates. Syntheses, properties and crystal and molecular structures of [Zn{mu#-SSi(OBu~t)_3}(acac)]_2 and [{(Bu~5tO)_3SiS}(H_2O)_2Zn{#Mu#-SSi(OBu~t)_3}Zn(acac){SSi( OBu~t)_3}]

摘要

Heteroleptic, neutral tri-tert-butoxysilanethiolates of zinc, incorporating acetylacaetonate (1) or acetylacetonate and water (2) as addition ligands, have been prepared by a reaction of zinc acetylacetonate with tri-tert-butoxysilanethiol in acetonitrile and characterized by IR, NMR and MS techniques. Crystal and molecular structures have been determined by single crystal X-ray structural analysis. Both are bimetallic with a distorted tetrahedral ligand arrangement at the zinc ZnO_2S_2 core. Complexes 1 and 2 are the first structurally characterized thiolates where the metal is also bonded to acetylacetonate and 2 is the first neutral aqua-ligated zinc thiolate.
