ring. Examples includepyridine(C5H5N), in which onenitrogen(N) replaces one CH group, andpurine(C5H4N4), in which two nitrogens replace two CH groups. Heterocyclic aromatic compounds, such asfuran(C4H4O),thiophene(C4H4S), andpyrrole(C4H4NH), contain five-membered rings in which oxygen (O...
(Diacetoxyiodo)benzene, with the chemical formula C8H7IO2, has the CAS number 3240-34-4. It appears as a white to light yellow crystalline powder with a faint odor. The basic structure of (Diacetoxyiodo)benzene consists of an iodine atom attached to a benzene ring, with two acetoxy groups...
{Ti8} ring using a deficient Ti source, accompanied with uncoordinated carboxylate oxygens, results in the formation of MIL-125-defect. Moreover, a secondary M(II) ion (M = Mn, Fe, Co, Ni, Cu, Zn) can be attached onto the metal vacancies to produce bimetallic MIL-125-X (Fig....
MD simulations of phase-Ih ice demonstrated that under compression, the column of oxygen atoms parallel to the compression direction would re-orient into a regular zigzag pattern50, and that under nanoindentation near the melting temperature, a quasi-liquid layer was formed at the ice-indenter ...
Alkylbenzenesulfonatesare the most common of the commercial anionic surfactants. Their general structure isp-alkylbenzenesulfonic acid,sodiumsalt (Figure 1) where the alkyl chain may range from C9 to C14 with thebenzenesulfonatemoiety attached in different proportions at each carbon atom from C2 to ...
2). Oxygen containing products were formed only over Fe-ZSM-5 (calcined both at 600 and 900°C). This result is consistent with the earlier statement with regard to the formation of α-oxygen species as a result of N2O decomposition over iron complexes accommodated only in the MFI structure...

The separation of the two oxygen substituents was very similar in the cubane and benzene systems (approx. 5.5 Å), despite the cubane ring being slightly smaller than the benzene ring, due to the shorter CO bond lengths observed in benzene (1.362 Å) than cubane (1.419 Å) due to ...
