Chromium(II) acetylacetonate - Wikipedia

WebMetal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH 3 COCHCOCH − 3) and metal ions, usually transition metals.The bidentate ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring. The simplest complexes have the formula M(acac) 3 … Web关键字搜索批量搜索. 批量下单. 分子砌块. 硼酸硼酸酯; Fragments smallest macaw species https://mariancare.org
