2-tert-Butyl-4,6-dinitrophenol

Abstract

The structure of the title compound, C10H12N2O5, has been determined and is found to have an intramolecular hydrogen bond between the phenol group and one of the 6‐nitro O atoms. The mol­ecule packs in a zigzag hydrogen‐bonded chain, consisting of an intermolecular hydrogen bond, parallel to the c axis, between the phenol group and a 4‐nitro O atom. The dihedral angle between adjacent molecules in the chain is 82 (3)°.

2-(4-Fluorophenyl)-2-oxo-1-(1H-1,2,4-triazol-1-yl)ethyl piperidine-1-carbodithiolate

“…The bond lengths and angles within the piperidine ring are also in good agreement with the earlier report by Yuan et al (2004). The C-F bond length [1.357 (2) Å ] is similiar to that found by Lynch & McClenaghan (2004)…”

2-Amino-4-(4-chloro-3-methylphenyl)-5-propyl-1,3-thiazolium iodide

“…The delocalization of the double bond in the N1-C2-N2 system of the title compound is very similar to delocalization observed in the case of 2-amino-4-p-tolyl-1,3-thiazolium chloride dihydrate (Lynch & McClenaghan, 2004). In (I), the C2-N2 bond length (Table 1) is shorter than the average [1.344 (2) Å ] for the other 12 members of the family in the CSD.…”

“…There are two additional compounds that have a naphthyl group instead of the benzene ring. Most of these structures were analyzed in terms of hydrogen-bonding networks, because the 2-amino-1,3-thiazole group can be a donor for two and an acceptor for three hydrogen bonds (Lynch et al, 2002;Lynch & McClenaghan, 2004).…”

1,3,4-Triphenyl-7-trifluoromethyl-1H-pyrazolo[3,4-b]quinoline at 293 and 100 K

“…This type of dynamic disorder of trifluoromethyl groups is often observed, e.g. in ethyl 4-[2-nitro-4-(trifluoromethyl)phenyl]piperazine-1-carboxylate (Lynch & McClenaghan, 2004) or {2-[3,5-bis(trifluoromethyl)-1H-pyrazol-1-ylmethyl]-6-(3,5-dimethyl-1Hpyrazol-1-ylmethyl)pyridine}methylpalladium(II) tetrakis[3,5bis(trifluoromethyl)phenyl]borate at 100 K (Guzei et al, 2008).…”
