1-[(2-Chloro-3,4-dimethoxy­benzyl­idene)amino]adamantane

The title compound, C₁₉H₂₄ClNO₂, was synthesized and characterized by single-crystal X-ray diffraction. The adamant­yl and benzene groups are bridged by an imine group, with a C—C=N—C torsion angle of −178.2 (2)°. Weak C—H...O and C—H...π inter­actions are found in the crystal packing.

2-[(2-Chloro-3,4-dimethoxy­benzyl­idene)amino]adamantane

The title compound, C₁₉H₂₄ClNO₂, is isomeric with the 1-[(2-chloro-3,4-dimethoxy­benzyl­idene)amino]adamantane structure reported in the previous paper [Isik, Köysal, Septioglu & Çalis (2005). Acta Cryst. E61, o1851-o1852].

trans-Diaquabis(ethyl­enediamine)zinc(II) 2-(sulfanilamido)­pyrimidine monohydrate

In the title compound, [Zn(C₄H₈N₄)(H₂O)₂](C₁₀H₉N₄O₂S)₂·H₂O, the Zn^II ion is octa­hedrally surrounded by two water O atoms [Zn—O = 2.68 (2) and 2.49 (2) Å] and the four N atoms of two ethylenediamine mol­ecules. Inter­molecular O—H...N, N—H...O and N—H...N hydrogen-bond inter­actions result in the formation of an intricate three-dimensional network.
