ABSTRACT
In the title compound, C(10)H(9)N(5)O(3)S, an intra-molecular N-Hâ¯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked via N-Hâ¯S hydrogen bonds into a zigzag chain along the b axis. C-Hâ¯O inter-actions are observed between the chains.
ABSTRACT
In the title compound, C(11)H(12)N(4)OS, an intra-molecular N-Hâ¯O hydrogen bond generates an S(6) ring motif. In the crystal, the mol-ecules form a helical chain along the a axis through an N-Hâ¯O hydrogen bond. These chains are extended by an N-Hâ¯S hydrogen bond and a C-Hâ¯π inter-action into a three-dimensional network.
ABSTRACT
In the title compound, C(15)H(12)N(4)OS, the dihedral angle between the nine-membered indolin-2-one ring system and the phenyl ring is 2.72â (7)°. Intra-molecular cyclic N-Hâ¯O and C-Hâ¯S hydrogen-bonding inter-actions [graph set S(6)] are present, as are weak N-Hâ¯N inter-actions [graph set S(5)]. In the crystal, mol-ecules form centrosymmetric cyclic dimers through pairs of N-Hâ¯O hydrogen bonds [graph set R(2) (2)(8)] and these are extended by C-Hâ¯S inter-actions. The crystal structure also features weak C-Hâ¯π inter-actions.
ABSTRACT
In the title compound, C(10)H(9)ClN(4)OS, an intra-molecular N-Hâ¯O hydrogen-bonding inter-action and an N-Hâ¯N inter-action generate ring motifs [graph sets S(6) and S(5), respectively]. In the crystal, mol-ecules form a chain through N-Hâ¯O hydrogen bonds, and these are extended by N-Hâ¯S hydrogen-bonding inter-actions into an infinite three-dimensional network. The crystal structure also exhibits weak C-Hâ¯π inter-actions.
ABSTRACT
The asymmetric unit of the title compound, [Ni(C(6)H(12)N(4)OS)(2)]Cl(2), contains two independent Ni(II) complex cations and four chloride anions. Each Ni(II) ion is six-coordinated in a distorted octa-hedral geometry by four N atoms from the two imine and two oxime groups and two S atoms from the thione group. In the crystal, the cations and anions are linked through N-Hâ¯Cl and O-Hâ¯Cl hydrogen bonds into infinite chains propagating along [10[Formula: see text]]. Weak inter-molecular C-Hâ¯O and C-Hâ¯Cl hydrogen bonds are also observed.
ABSTRACT
In the title compound, C(15)H(11)ClN(4)OS, the dihedral angle between the nine-membered 5-chloro-indolin-2-one ring system and the benzene ring is 10.00â (6)°. Intra-molecular cyclic N-Hâ¯O and C-Hâ¯S hydrogen-bonding inter-actions [graph set S(6)] are present in the N-N-C-N chain between the ring systems. In the crystal, mol-ecules form centrosymmetric cyclic dimers through inter-molecular N-Hâ¯O hydrogen bonds [graph-set R(2) (2)(8)] and are extended by C-Hâ¯Cl inter-actions into infinite chains which propagate along [100].
ABSTRACT
In the title compound, C(16)H(14)N(4)OS, the dihedral angle between the nine-membered 5-methyl-indolin-2-one ring system and the benzene ring is 10.21â (7)°. Intra-molecular cyclic N-Hâ¯O and C-Hâ¯S hydrogen-bonding inter-actions [graph set S(6)] are present within the N-N-C-N chain between the ring systems. In the crystal, mol-ecules form centrosymmetric cyclic dimers through pairs of N-Hâ¯O hydrogen bonds [graph set R(2) (2)(8)].
