AI Article Synopsis
- The complex [Lu(CHOP)]·2CH is created from a reaction involving potassium 2,6-di--butyl-4-methyl-phenyl ethyl phosphate and LuCl in water, followed by vacuum drying and heptane recrystallization.
- Its crystal structure is triclinic at 120 K, featuring a binuclear [Lu(μ-OPO)] core, with the organophosphate ligand showing multiple coordination modes with lutetium.
- This complex is notable for its potential as a precatalyst in acrylo-nitrile polymerization, demonstrating effective catalytic activity under mild conditions.
Article Abstract
The title complex, [Lu(CHOP)]·2CH, was formed in the reaction between potassium 2,6-di--butyl-4-methyl-phenyl ethyl phosphate, [K(2,6- Bu-4-MeCH-O)(EtO)PO], and LuCl(HO) in water, followed by vacuum drying and recrystallization from heptane. Its crystal structure has triclinic ( [Formula: see text]) symmetry at 120 K. The lutetium tris-(phosphate) complex has a binuclear [Lu(μ-OPO)] core and the organophosphate ligand exhibits κ,' terminal and μ-κ:κ' bridging coordination modes with the Lu ion being sixfold coordinated. The complex is of inter-est as a precatalyst in the acrylo-nitrile polymerization process and displays good catalytic activity under mild conditions.

Characterization and formation of the biomineral aragonite structures of the Noah's Ark shell ( L.,1758) were studied from structural, morphogenetic, and biochemical points of view. Structural and morphological features were examined using X-ray diffraction, field-emission scanning electron microscopy, and atomic force microscopy, while thermal properties were determined by thermogravimetric and differential thermal analyses.

Inosine 5'-monophosphate dehydrogenase (IMPDH) is a promising antibiotic target. This enzyme catalyzes the NAD-dependent oxidation of inosine 5'-monophosphate (IMP) to xanthosine 5'-monophosphate (XMP), which is the rate-limiting step in guanine nucleotide biosynthesis. Bacterial IMPDH-specific inhibitors have been developed that bind to the NAD site.

Catalytic elimination through an oxidative decomposition pathway is the most promising candidate for the purification of chlorinated volatile organic compound (CVOC) pollutants, but the complicated mechanisms and the formation pathways of hydrogenated byproducts still need to be clearly revealed. Herein, W/ZrO, as a structure-tunable catalyst, is used to catalytically oxidize dichloromethane (DCM) and clarify the formation pathway of monochloromethane (MCM). Crystal engineering of ZrO tailors surface WO species; practically, the predominant Zr-WO clusters and crystalline WO can be obtained on monoclinic (m-ZrO) and tetragonal (t-ZrO) phases.

In this work, a theoretical approach is developed to investigate the structural properties of ionic microgels induced by a circularly polarized (CP) electric field. Following a similar study on chain formation in the presence of linearly polarized fields [T. Colla , , 2018, , 4321-4337], we propose an effective potential between microgels which incorporates the field-induced interactions a static, time averaged polarizing charge at the particle surface.

By virtue of being atomically thin, the electronic properties of heterostructures built from two-dimensional materials are strongly influenced by atomic relaxation. The atomic layers behave as flexible membranes rather than rigid crystals. Here we develop an analytical theory of lattice relaxation in twisted moiré materials.
