Trans-Bis(ethyl-enediamine-?N,N')bis-(6-methyl-2,2,4-trioxo-3,4-dihydro-1,2?,3-oxathia-zin-3-ido-?N)copper(II).

ABSTRACT: In the crystal structure of the title compound, [Cu(C(4)H(4)NO(4)S)(2)(C(2)H(8)N(2))(2)], the Cu(2+) ion resides on a centre of symmetry. The environment of Cu(2+) ion is a distorted octa-hedron. The axial bond lengths between the Cu(II) ion and the N atoms are considerably longer than the equatorial bond distances between the Cu(II) ion and the N atoms of the ethyl-enediamine ligand as a consequence of the Jahn-Teller effect. The mol-ecular conformation is stabilized by intra-molecular N-H?O hydrogen bonds. In the crystal, mol-ecules are connected by inter-molecular N-H?O hydrogen bonds into chains running along the a axis.

Project description:The title acesulfamate complex, [Pd(C(30)H(22)FO(2)P(2))(C(4)H(4)NO(4)S)], contains a four-coordinate Pd(II) ion with the expected, although relatively distorted, square-planar geometry where the four L-Pd-L angles range from 79.58 (8) to 102.47 (7)°. The acesulfamate ligand is N-bound to Pd [Pd-N = 2.127 (2) Å] with a dihedral angle of 76.35 (6)° relative to the square plane. Relatively long phen-yl-acesulfamate C-H⋯O and phen-yl-fluorine C-H⋯F inter-actions consolidate the crystal packing.

3,3'-(Ethane-1,2-di-yl)bis-(3,4-dihydro-2H-1,3-benzoxazine).

Project description:The title compound, C(18)H(20)N(2)O(2), was prepared by Mannich-type reaction of phenol, ethane-1,2-diamine and formaldehyde. The heterocyclic rings adopt half-chair conformations. The acyclic methyl-ene groups attached to the N atoms are in an axial position. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into dimers. These dimers are further connected via C-H?? contacts.

Project description:The asymmetric unit of the title compound, C(20)H(24)N(2)O(2), contains one half-mol-ecule, which is completed by inversion symmetry. In the crystal, mol-ecular chains are formed through non-classical C-H⋯O hydrogen bonds, formed between axial H atoms of the oxazine ring and a O atom of a neighboring mol-ecule.

Bis(ethyl-enediamine-?N,N')bis-(phenytoinato-?N)cobalt(II).

Project description:THE TITLE COMPOUND [SYSTEMATIC NAME: bis(2,5-dioxo-4,4-diphenylimidazolidin-1-ido-?N(1))bis(ethylenediamine-?(2)N,N')cobalt(II)], [Co(C(15)H(11)N(2)O(2))(2)(C(2)H(8)N(2))(2)], has site symmetry . The Co(II) cation is located on an inversion center and coordinated by two phenytoin anions and two ethyl-enediamine ligands in a distorted octa-hedral geometry. In the phenytoin anion, the two phenyl rings are twisted with respect to the central hydantoin ring, making dihedral angles of 77.49?(16) and 64.55?(15)°. Intra-molecular and inter-molecular N-H?O hydrogen bonding is present in the crystal structure.

catena-Poly[[bis-(ethyl-enediamine)copper(II)]-?-sulfato].

Project description:In the title compound, [Cu(SO(4))(C(2)H(8)N(2))(2)](n), the Cu, S and two O atoms lie on a mirror plane. The Cu atom is in a distorted octa-hedral environment and the ethyl-enediamine ligand is in a gauche conformation. The sulfate dianion is bridging, forming a one-dimensional chain. A two-dimensional net parallel to (001) is generated by N-H?O hydrogen bonding between the chains.

Project description:In the title compound, [Co(C(8)H(6)N(3))(2)(C(2)H(8)N(2))]NO(3)·H(2)O, the Co(III) ion is coordinated by four N atoms from two 2-(pyridin-2-yl)-1,3-imidazol-1-ide ligands and two N atoms of ethyl-enediamine in a distorted octa-hedral geometry. In the crystal, classical N-H?N(O) and O-H?N(O) hydrogen bonds connect all the isolated components together to yield a three-dimensional structure.

Diethyl 2,6,11-trioxo-2,3-dihydro-1H-anthra[1,2-d]imidazole-1,3-diacetate.

Project description:The title compound, C(23)H(20)N(2)O(7), consists of three fused six-membered rings (A, B and C) and one five-membered ring (D), linked to two ethyl acetate groups. The four fused rings are slightly folded around the O=C?C=O direction of the anthraquinone system, with a dihedral angle of 3.07?(8)° between the fused five- and six-membered rings (C and D) and the terminal ring (A). The planes through the atoms forming each acetate group are nearly perpendicular to the mean plane of the anthra[1,2-d]imidazole system, as indicated by the dihedral angles between them of 79.94?(9) and 85.90?(9)°. The crystal packing displays non-classical C-H?O hydrogen bonds.

Ethyl 2-(3,4-dimethyl-5,5-dioxo-1H,4H-benzo[e]pyrazolo-[4,3-c][1,2]thia-zin-1-yl)acetate.

Project description:In the title mol-ecule, C(15)H(17)N(3)O(4)S, the heterocyclic thia-zine ring adopts a twist-boat conformation, which differs from that in related compounds, with adjacent S and C atoms displaced by 0.981?(4) and 0.413?(5)?Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The mean plane of the benzene ring makes a dihedral angle of 23.43?(14)° with the mean plane of the pyrazole ring. In the crystal, mol-ecules are connected by weak C-H?O hydrogen bonds to form a three-dimensional network. The H atoms of the methyl group attached to the pyrazole ring were refined over six sites with equal occupancies.

3,3'-(Ethane-1,2-diyl)bis(6-meth-oxy-3,4-dihydro-2H-1,3-benzoxazine) mono-hydrate.

Project description:The asymmetric unit of the title compound, C(20)H(24)N(2)O(4)·H(2)O, contains one half-organic mol-ecule (an inversion centre generates the other half of the mol-ecule) and a half-mol-ecule of water (the O atom has site symmetry 2). The near planarity of the fused-benzene ring is illustrated by the very small deviations of all the atoms from the plane [largest deviation = 0.0092 (11) Å. The six-membered N,O-containing ring adopts a half-chair conformation. The observed N-CH(2) and CH(2)-O bond lengths can be correlated to the manifestation of an anomeric effect in the N-CH(2)-O unit. In the crystal, the mol-ecules are connected into zigzag chains parallel to [001] through O-H⋯N hydrogen bonds formed between the oxazinic N atom and the solvent water mol-ecule. The chains are consolidated by C-H⋯O inter-actions.
