N-[2-(3,4-Dimeth-oxy-phenyl)eth-yl]-N-methyl-naphthalene-1-sulfonamide.

ABSTRACT: In the title compound, C(21)H(23)NO(4)S, the dihedral angle between the naphthalene residue and the benzene ring is 7.66 (3)°. In the molecule, there are some short C-H⋯O interactions. In the crystal, the structure is stabilized by weak intra-molecular C-H⋯O hydrogen bonds and the crystal structure is stabilized by weak C-H⋯O, C-H⋯π and π-π [centroid-centroid distance = 3.710 (2) Å] inter-actions.

N-[2-(3,4-Dimeth-oxy-phen-yl)eth-yl]-N-methyl-benzene-sulfonamide.

Project description:In the title compound, C(17)H(21)NO(4)S, the phenyl and dimeth-oxy-phenyl rings are almost perpendicular to each other, making a dihedral angle of 82.57 (5)°. The structure is stabilized by inter-molecular C-H⋯O inter-actions and the packing is further enhanced by C-H ⋯π inter-actions.

N-[2-(3,4-Dimeth-oxy-phen-yl)eth-yl]-N,4-dimethyl-benzene-sulfonamide.

Project description:In the title compound, C(18)H(23)NO(4)S, the dihedral angle between the two aromatic rings is 29.14?(7)°. The S atom has a distorted tetra-hedral geometry [106.15?(9)-119.54?(10)°]. The crystal structure exhibits weak C-H?O and ?-? inter-actions.

N-(3-Eth-oxy-phen-yl)-4-methyl-benzene-sulfonamide.

Project description:In the title compound, C(15)H(17)NO(3)S, the two aromatic rings make a dihedral angle of 69.42?(9)° with each other and the bridging C-N-S-C torsion angle is 65.76?(16)°. Weak intra-molecular C-H?O inter-actions may affect the mol-ecular conformation. Two neighbouring mol-ecules generate a hydrogen-bonded dimer about a center of inversion through a pair of inter-molecular N-H?O inter-actions, forming an R(2) (2)(8) ring motif. Furthermore, two inter-molecular C-H?? inter-actions contribute to the stability of the crystal packing.

4-Methyl-N-[(S)-1-phenyl-eth-yl]benzene-sulfonamide.

Project description:In the title compound, C(15)H(17)NO(2)S, the dihedral angle between the aromatic rings is 14.47 (8)°. The mol-ecule is bent at the N atom, with a C-SO2-NH-C torsion angle of 79.06 (13)°. In the crystal structure, the sulfonamide groups are hydrogen bonded via N-H⋯O links, forming chains of mol-ecules along the crystallographic b axis. π-π inter-actions [centroid-centroid distance = 3.81 (3) Å] also occur.

Tetra-kis(μ-3,4-dimeth-oxy-phenyl-acetato)-bis-[(3,4-dimeth-oxy-phenyl-acetato)(1,10-phenanthroline)holmium(III)].

Project description:In the centrosymmetric title compound, [Ho(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Ho(III) atom is nine-coordinated by seven O atoms from the 3,4-dimeth-oxy-phenyl-acetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) mol-ecule. The L ligands are coordinated to the Ho(III) ions in three modes: chelating, bridging and bridging-tridentate. Intra-molecular C-H⋯O inter-actions occur. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions and weak aromatic π-π inter-actions between phen mol-ecules and the aromatic rings of the L ligands [centroid-centroid distance = 3.821 (2) Å].

(E)-1-(2,2-Dimeth-oxy-eth-yl)-2-(nitro-methyl-idene)imidazolidine.

Project description:In the title compound, C(8)H(15)N(3)O(4), the 2-(nitro-methyl-ene)imidazolidine fragment is close to being planar (r.m.s. deviation = 0.027 Å), which may be correlated with delocalization of the electrons and the effect of the strongly electron-withdrawing NO(2) group. An intra-molecular N-H⋯O link generates an S(6) ring. The same H atom also forms a weak inter-molecular N-H⋯O hydrogen bond, which results in C(7) chains propagating in [010].

N-(7-Eth-oxy-1H-indazol-4-yl)-4-methyl-benzene-sulfonamide.

Project description:The mol-ecule of the title heterocyclic compound, C(16)H(17)N(3)O(3)S, is bent at the S atom with an C-SO(2)-NH-C torsion angle of 80.17?(8)°. The phenyl substituent at the S atom is rotated out of the plane of the 1H-indazole ring [inter-planar angle = 46.24?(8)°]. In the crystal, inter-molecular N-H?N and N-H?O hydrogen bonds build up a ribbon developing parallel to the b-axis direction. C-H?O hydrogen bonds link these ribbons, forming a layer parallel to the bc plane.

(S)-Methyl 2-benzamido-3-(3,4-dimeth-oxy-phen-yl)propano-ate.

Project description:The dimethoxypbenzene ring in the title compound, C(19)H(21)NO(5), is gauche to the amide group and anti to the ester group. The chirality was confirmed to be S from two-dimensional NMR spectroscopy. In the crystal, N-H?O and C-H?O hydrogen bonds and several short-contact inter-actions (2.07-3.45?Å) create chains parallel to [110]. The phenyl ring is disordered over two orientations in a 0.54?(2):0.46?(2) ratio.

Project description:The asymmetric unit of the title compound, C(15)H(14)ClNO(2), contains two mol-ecules with significantly different conformations: the dihedral angles between the 4-chloro-aniline and 3,4-dimeth-oxy-phenyl (excluding C atoms) moieties are 19.68 (7) and 45.54 (4)°. In the crystal, the mol-ecules are linked by C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions.
