The structures and catalytic behaviors of two new complexes based on bifunctional tetrazole-carboxylate connector

Abstract

Two transition metal coordination complexes [Co(Tppebc) 2 (Py)(H 2 O)] n (1) and [Ni(Tppebc) 2 (Py)(H 2 O)] n (2) (Py = pyridine, phenyl-4-yl) phenyl)-2-ethoxy-3H-benzimidazole-4-carboxylic acid) have been prepared by a hydrothermal method. The structural unit of complexes 1 and 2 adopts similar distorted octahedra geometry. Furthermore, both of those complexes feature a 1D chain and can be further extended to a higher-dimensional architecture through π•••π stacking and hydrogen bonding. The catalytic property of complexes 1 and 2 were researched in the green catalytic process of the oxidative 2,6-di-tert-butylphenol (DBP). The high conversion and good selectivity results strongly indicate that both of the title complexes are catalytically active under the optimized reaction conditions.

An Overview of Recent Progress in Engineering Three-Dimensional Scaffolds for Cultured Meat Production

“…Natural plant tissues, like green and edible spinach leaves, celery, and apple tissue [ 41 ], show obvious vascularity and porous morphology (anisotropic structure) to facilitate oxygen and nutrient transport, serving a favorable cell environmental platform [ 15 ]. Allan et al demonstrated that a decellularized grass leaf scaffold with natural morphology supported the attachment and proliferation of mouse C2C12 cells and induced the cells’ alignment [ 42 ].…”
