In the crystal structure of the title compound, C(14)H(12)N(2)O(2), the molecule lies about a twofold axis; two carbonyl groups and the H atoms of the N-N bond are in a trans orientation with respect to each other. In the crystal, each molecule is linked to the other and vice versa by intermolecular N-H.O hydrogen bonds between the amide hydrogen and the O atoms of neighbouring molecules to form two ten-membered rings, each of which has the graph-set motif C4R(2)(2)(10). This extends as a polymeric chain along the c axis.
In the crystal structure of the title complex, [Au(C(7)H(14)NS(2))(C(18)H(15)P)(2)].C(4)H(10), the Au atom is in a distorted tetrahedral environment consisting of the two P atoms of the triphenylphosphine ligands and the two S atoms of the diisopropylthiocarbamate ligand. The molecular structure and packing are stablized by van der Waals interactions.
In the title complex, [RuCl(2)(C(16)H(36)N(4))]I(3), the overall symmetry of the centrosymmetric cation is approximately C(2h) and the I(-3) anions are slightly asymmetric. The I.I distance is 4.313 (1) A. The cations and the linear anions are arranged in alternate layers and thus form the intercalating structure.
The whole molecule of the title compound, C(19)H(14)N(4)O(2), is essentially planar, with a highly conjugated pi system. In the crystal, the molecules are packed as chains along the [011] direction connected by O-H.N intermolecular hydrogen bonds.
The crystal structure of the title compound, C(15)H(14)N(2)O(2). H(2)O, is in the keto tautomeric form and the configuration at the azomethine C=N double bond is E. The molecule is non-planar, with a dihedral angle of 27.3 (1) degrees between the aromatic rings. The crystal structure is stabilized by extensive hydrogen bonding involving the water molecule and hydrazone moiety.
In the crystal structure of the title compound, C(3)H(3)NO(2)S(2), the four-membered C(2)S(2) ring is planar, as is the whole molecule. The short intramolecular S.O distance of 2.687 (2) A shows the five-atom system to be conjugated. The molecules pack as a two-dimensional network in the (010) plane through short intermolecular S.O [2.900 (2) and 3.077 (2) A] interactions.
In the crystal structure of the title compound, C(8)H(10)N(2)S(2), the molecules are linked by N-H.S hydrogen bonds between the imino group and the thione-S atoms to form a chain along the b axis. The dithiocarbazate moiety is rotated by 85.8 (2) degrees with respect to the phenyl ring.
In the crystal structure of the title compound, C(11)H(16)N(4)OS, the phenyl ring and the thiosemicarbazone moiety from a dihedral angle of 7.7 (1) degrees. The crystal structure is governed by N-H.O and O-H.S hydrogen bonds leading to the formation of a two-dimensional network.
A donor-acceptor compound, diaqua-1kappaO,2kappaO-[&mgr;-11, 23-dimethyl-3,7,15,19-tetraazatricyclo[19.3.1.1(9,13)]hexacosa-1(25), 2,7,9,11,13(26),14,19,21,23-decaene-25,26-diolato-1kappa(4)N(3),N(7), O(25),O(26):2kappa(4)N(15),N(19),O(25),O(26)]dizinc(II) diperchlorate bis(8-methylquinoline) ethanol disolvate, [Zn(2)(C(24)H(26)N(4)O(2))(H(2)O)(2)](ClO(4))(2).2C(10)H(9)N. 2C(2)H(6)O, obtained by the reaction of a dinuclear zinc(II) complex of a Robson macrocycle (acceptor) and 8-methylquinoline (donor), lies about an inversion centre and the coordination about the unique Zn atom is a distorted square pyramid. The fifth coordination site is occupied by the water molecule, Zn-O = 2.016 (2) A, and the average macrocyclic Zn-O and Zn-N distances are 2.059 (6) and 2.059 (3) A, respectively.

The title compounds, 10-benzoylamino-1,2,3,4,5,6,7,8,9, 10-decahydroacridine-1,8-dione monohydrate, C(20)H(20)N(2)O(3).H(2)O, and 10-p-toluoylamino-1,2,3,4,5,6,7,8,9,10-decahydroacridine-1, 8-dione monohydrate, C(21)H(22)N(2)O(3).H(2)O, consist of partially hydrogenated acridine moieties with one benzoylamino substituent on the central ring. The acridine moiety suffers considerable deviations from planarity. The central ring in the acridine moiety is a boat, while the outer rings adopt sofa conformations.
