ABSTRACT

The structure of the title compound, NH4+.C12H22O2PS2-, consists of a polymeric arrangement of ammonium cations and O,O-dicyclohexyl phosphorodithioate anions linked through N-H...O and N-H...S hydrogen bonds. These interactions result in the formation of (100) sheets.

ABSTRACT

The title compound, C24H26BrN3OS, crystallizes in the triclinic space group P-1, with two independent molecules in the asymmetric unit. The molecules adopt an E geometry about the azomethine C=N double bond. The structure is stabilized as dimers by N-H...N hydrogen bonding. C-H...pi and pi-pi interactions are also effective in the crystal packing.

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 structure of the title compound, C20H18O2, consists of a dimeric arrangement of benzofuran molecules around an inversion centre, linked via C-H...O hydrogen bonds. There are also C-H...pi ring interactions. All these interactions result in the formation of infinite chains parallel to the [100] axis. The cyclobutane ring is puckered, with a dihedral angle of 29.03 (13) degrees between the two three-atom planes.

ABSTRACT

The structure of the title compound, C(15)H(12)N(2)O(4), consists of a polymeric arrangement, around inversion centres, of molecules linked through O-H.N and O-H.O hydrogen bonds; there are also intramolecular hydrogen bonds. All these hydrogen-bond interactions result in the formation of infinite chains parallel to the [010] direction. The oxime group has an E conformation.
