1-(4-Methoxyphenyl)ethane-1,2-diyl 1,1′-biphenyl-2,2′-dicarboxylate
In the title mol-ecule, C(23)H(18)O(5), the meth-oxy-substituted benzene ring makes dihedral angles of 65.12 (4) and 88.55 (4)° with the other two benzene rings. These two benzene rings form a dihedral angle of 45.70 (4)°. In the crystal, mol-ecules are linked into inversion dimers by pairs of weak C-H⋯O hydrogen bonds.
متن کاملSynthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...

متن کامل4-Aminobenzoic acid–1,2-bis(4-pyridyl)ethane (2/1)
In the title compound, C(12)H(12)N(2)·2C(7)H(7)NO(2), the 4-amino-benzoic acid mol-ecules are linked by O-H⋯N hydrogen bonds to 1,2-bis-(4-pyrid-yl)ethane, forming linear hydrogen bonded chains parallel to [21]. The structure exhibits a hydrogen-bonding network involving COOH⋯N(pyrid-yl) and amine and carb-oxy-lic N-H⋯ O inter-actions. In addition, π-π stacking inter-actions [centroid-centroid ...
متن کامل1-(Biphenyl-4-ylcarbonyl)-3-(2-chloro-4-nitrophenyl)thiourea
The benzene rings of the biphenyl group in the title compound, C(20)H(14)ClN(3)O(3)S, are nearly coplanar [maximum deviation = 0.20 (3) Å]. The mean plane of the biphenyl group forms a dihedral angle of 5.24 (7)° with the aromatic ring of the nitro-chloro-benzene group. Intra-molecular N-H⋯Cl, N-H⋯O and C-H⋯S hydrogen bonds stabilize the cis-trans conformation of the mol-ecule. In the crystal, ...
