ABSTRACT: The title complex, [Co(C2H3O2)2(C7H6N2S)2], contains a Co centre with a slightly distorted tetrahedral coordination geometry, involving two acetate ligands and two N atoms from the thiazole moiety [Co-O = 2.0025 (14) and 1.9953 (16) A, and Co-N = 2.0524 (18) and 2.0568 (18) A]. The interplanar angle between the two benzothiazole moieties is 77.86 (3) degrees . The amine groups, acting as donors, participate in intra- and intermolecular N-H...O hydrogen bonds, with N...O distances in the range 2.806 (2)-2.857 (2) A.

ABSTRACT: In the title compounds, C18H20N2O2, (I), and C14H11N3O4.0.5H2O, (II), respectively, the oxime groups have an E configuration. In (I), the molecules exist as polymers bound by intermolecular C-H...O and O-H...N hydrogen bonds around inversion centres. In (II), intermolecular OW-H...N, OW-H...O and O-H...OW interactions stabilize the molecular packing.

ABSTRACT: The crystal structure of the title compound, C14H14N2O, determined at 293 K, shows that the molecule is approximately planar in the solid state and that the aromatic rings have a trans configuration with respect to the azo double bond, as found for other diazene derivatives. The packing can be described as a polymeric arrangement of molecules linked through O-H...N and C-H...O hydrogen bonds and close contacts. These intermolecular interactions result in the formation of infinite chains parallel to the b axis.

ABSTRACT: The structure of the title compound, C(16)H(16)N(2)O(2), consists of a dimeric arrangement around an inversion centre of acetamidine molecules linked via O-H.N hydrogen bonds. There are also H.pi-ring interactions. All these interactions result in the formation of infinite chains parallel to the (101) axis. The oxime group has an E conformation.
