4-Amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide–benzoic acid (1/1)
The constituents of the title co-crystal, C12H14N4O2S·C7H6O2, are connected by an eight-membered hetero-synthon {⋯NCNH⋯OCOH}, whereby the carboxylic acid forms donor and acceptor hydrogen bonds with
Electronic structure and normal vibrations of CH3(OCH2CH2)nOCH3-M+-CF3SO3- (n = 2-4, M = Li, Na, and K).
TLDR
Electronic structure and the vibrational frequencies of glyme-MTf complexes have been derived from ab initio Hartree-Fock calculations and suggest stronger binding of lithium to the diglyme than the tri- or triglyme analogues.
Persistence of the {…HOCO…HCN} heterosynthon in the co-crystals formed between anthranilic acid and three bipyridine-containing molecules
Abstract Co-crystals formed between anthranilic acid and each of 4,4′-bipyridine (1), 1,2-trans-1,2-bis(4-pyridyl)ethene (2) and 1,2-bis(4-pyridyl)ethane (3) have been formed from solutions
Crystal and Molecular Structures of the 2:1 Cocrystal of 4-Nitrophenylacetic acid and N,N′-bis(pyridin-3-ylmethyl)oxalamide, and with the Thioxalamide Analogue
The common feature of each of the title 2:1 cocrystals is the formation of the O–H···N(pyridyl) hydrogen bonds leading to three-molecule aggregates. The persistent formation of the O–H···N(pyridyl)
2 : 1 Co-crystals of p-nitrophenylacetic acid with three isomeric n-pyridinealdazines, n = 2, 3 and 4, featuring the {… HOCO … N(py)} heterosynthon
Abstract Crystal and molecular structures of 2 : 1 co-crystals formed between p-nitrophenylacetic acid and three isomeric n-pyridinealdazines, n = 2(1), 3(2) and 4(3), are described in which the
Benzoic acid–2,9-dimethylphenanthroline (1/1)
The constituents of the title 1:1 co-crystal, C7H6O2·C14H12N2, are connected into dimeric aggregates by a bifurcated O—H⋯N hydrogen bond; the hydroxyl-H atom is hydrogen bonded to the two N atoms of
4-Aza-1-azoniabicyclo[2.2.2]octane–2-aminobenzoate–2-aminobenzoic acid (1/1/1)
TLDR
An intramolecular N—H⋯O hydrogen bond occurs in the anion and in the neutral 2-aminobenzoic acid molecule of the title compound, C6H13N2 +·C 7H6NO2 −·C7H7NO2.
2-(4-Chlorophenyl)acetic acid–2-{(E)-[(E)-2-(2-pyridylmethylidene)hydrazin-1-ylidene]methyl}pyridine (1/1)
In the crystal of the title 1:1 adduct, C8H7ClO2·C12H10N4, the components are linked by an O—H⋯N hydrogen bond between the carboxylic acid and one of the pyridine N atoms. In the acid, the carboxylic
1,2,4,5-Tetrafluoro-3,6-diiodobenzene–4-(pyridin-4-ylsulfanyl)pyridine (1/1)
TLDR
The asymmetric unit of the title 1:1 adduct, C10H8N2S·C6F4I2, comprises a half-molecule of 1,2,4,5-tetrafluoro-3,6-diiodobenzene, and half a 4-(pyridin-4-ylsulfanyl)pyridine molecule, generating a supramolecular chain with a step-ladder topology.
