Terephthalic acid–2,2′-dimethyl-1,1′-(butane-1,4-diyl)dibenzimidazole (2/3)
In the crystal structure of the title compound, 2C(8)H(6)O(4)·3C(20)H(22)N(4), there are three independent 2,2'-dimethyl-1,1'-(butane-1,4-di-yl)dibenzimidazole mol-ecules, each of which lies on an inversion centre. The terephthalic acid mol-ecules are linked to adjacent 2,2'-dimethyl-1,1'-(butane-1,4-di-yl)dibenzimidazole mol-ecules via O-H⋯N hydrogen bonds.

The title compound, C(20)H(22)O(4)S(2), was synthesized by the reaction of 1,4-dibromo-butene with methyl thio-salicylate. The aliphatic segment of this ligand is in an all-trans conformation. The bridging chain, -S-(CH(2))(4)-S-, is almost planar (r.m.s. deviation for all non-H atoms: 0.056 Å) and its mean plane forms dihedral angles of 16.60 (7) and 5.80 (2)° with the aromatic rings. In the c...

About 20 years have elapsed since those studies were done. During this period, many changes that might influence teenage reproductive behavior and how it is viewed have taken place within the industrialized world. The proportion of births to unmarried women has risen,2 and nonmarital childbearing is more acceptable, both among adolescents and among women older than 20. Access to contraception a...

In the title compound, C36H36N2, a product of the condensation reaction of 2,3-dimethyl-6-phenyl-vinyl-benzenamine and 2,3-butane-dione, the complete mol-ecule is generated by the application of an inversion centre. The central C-C bond in the 1,4-di-aza-butadiene fragment is trans-configured and situated about the inversion center. The dihedral angle between the ring attached to N and the 1,4-...

In the title compound, C(14)H(30)N(2) (2+)·2Br(-)·2CH(3)OH, two terminal C atoms of the butane chain are connected to two N atoms of the 1-methyl-pyrollidines, forming a linear diquaternary ammonium cation. The cation lies across a centre of inversion located between the two central C atoms of the butane chain. The asymmetric unit therefore comprises one half-cation, a bromide anion and a metha...
