The title compound, C28H22O2, is a inter­mediate in the synthesis of 10,10′-dibromo-9,9′-bianthracen­yl. The mol­ecule forms both intra- and inter­molecular O—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]

The title compound, C12H10ClNO2, was synthesized by the reaction of ethyl cyano­caetate with 4-chloro­benzaldehyde in ethanol under microwave irradiation. In the crystal structure, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into centrosymmetric dimers, which are held together by van der Waals forces. [ABSTRACT FROM AUTHOR]

In the title compound, C4H3BrO3S2, all bond lengths and angles are within normal ranges. The crystal packing exhibits intermolecular O—H...O hydrogen bonds, which link the molecules into chains extended along the c axis. [ABSTRACT FROM AUTHOR]

In the title compound, C23H26N4OS, the fused tricyclic system is essentially planar. The crystal stacking is mainly due to π–π inter­actions and inter­molecular N—H⋯O hydrogen-bond inter­actions. [ABSTRACT FROM AUTHOR]

The title compound, C14H13N3O3S, has been synthesized as a potent fungicidal agent. The 1,3-thiazolidine ring is approximately planar and makes a dihedral angle of 84.9 (2)° with the phenyl ring. There are weak intramolecular C—H...O and C—H...N hydrogen bonds, which stabilize the molecular structure. [ABSTRACT FROM AUTHOR]

In the title salt, C8H20N22+ SO4 2-a, a ten-membered hydrogenbonded ring (C3H2N2O2S) is observed involving the two ammonium groups and two O atoms of the sulfate ion. A three-dimensional hydrogen-bond network is constructed whereby every sulfate anion is linked to five adjacent (1R,3S)-1,2,2-trimethylcyclopentane-1,3-diammonium cations by N—HȮO interactions.
