Fast Synthesis of Ligand-Coordinated Chromium (II) Acetate with Quadruple Bonds by Seed-Mediated Growth

Abstract

A new way to prepare single crystals of ligand-coordinated chromium (II) acetate with quadruple bonds is presented. Coordination of water and pyridine with crystal growth occur by seed-mediated growth. The product was obtained as crystals with well-defined facets. Raman spectroscopy confirmed the high quality and purity of the products. Mechanism studies showed that the growth reaction is driven by heterogeneous crystallization at the interface of the seeds. Seed-mediated growth results in the high quality and large size of the crystals with improved yield for shorter reaction time.
