The whole mol-ecule of the title compound, C14H14N4, is generated by twofold rotation symmetry. The twofold axis bis-ects the central -CH2-CH2- bond and the planes of the pyridine rings are inclined to one another by 65.60 (7)°. In the crystal, there are no significant inter-molecular inter-actions present.

In the title mol-ecule, C(18)H(14)N(2)O(3), O-H⋯N and N-H⋯O hydrogen bonds influence the mol-ecular conformation; the benzene and naphthalene planes are inclined at a dihedral angle of 11.54 (5)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains running in the [01] direction.

The title compound, C(15)H(10)ClNO, is a functionalized isoxazole with a chloro-phenyl and a phenyl substitutent. The mean plane of the isoxazole ring is inclined to those of the two benzene ring mean planes by 38.32 (16) and 43.91 (18)°.

In the title mol-ecule, C(15)H(11)ClO(2), the mean planes of the benzene and phenyl rings are inclined at 69.06 (11)° with respect to each other. The crystal structure is stablized by strong inter-molecular O-H⋯O hydrogen bonds between the acid groups of pairs of mol-ecules related by inversion centers.

An investigation of the identifiable real-time sonographic features of the normal infant brain in the horizontal, coronal, inclined coronal, and midsagittal planes was undertaken. Correlations were made of sonograms of intact brains in vitro, corresponding brain sections, and sonograms in vivo. A large number of anatomic structures could be consistently depicted including cisterns, fissures, fa...

The title compound, C(28)H(30)N(2)OS(2), was obtained by thio-nation of 3',6'-bis-(diethyl-amino)-3H-spiro-[isobenzofuran-1,9'-xan-thene]-3-one with 2,4-bis-(p-methoxy-phen-yl)-1,3-dithia-diphos-phetane disulfide (Lawesson's reagent). The planes of the two benzene rings of the xanthene system are inclined at a dihedral angle of 17.4 (1)°, and the plane of the dithio-phthalide group and the plan...

in this paper, a multi-objective method is used to optimize a heat recovery steam generator (hrsg). two objective functions have been used in the optimization, which are irreversibility and hrsg equivalent volume. the former expresses the exergetic efficiency and the latter demonstrates the cost of the hrsg. decision variables are geometric and operational parameters of the hrsg. the results of...

The title compound, C(19)H(12)Br(3)N, was synthesized by N-alkyl-ation of 1-bromo-4-(bromo-meth-yl)benzene with 3,6-dibromo-9H-carbazole. There are two unique mol-ecules in the asymmetric unit. The carbazole ring system is essentially planar, with a mean deviation of 0.0402 Å for one mol-ecule and 0.0279 Å for the other. The carbazole planes are inclined to the benzene ring planes at dihedral a...

The scanning two-photon fluorescence microscope produces optically sectioned images from the focal plane. It is sometimes desirable to acquire images from other planes of the specimen that are inclined with respect to the focal plane. In this Letter, we discuss the issues concerned with acquiring such images together with the effects of the inclination angle on image resolution and sectioning s...

In the title compound, C29H24Cl2N2O4, the mean planes of the two indole ring systems (r.m.s. deviations = 0.1249 and 0.0075 Å) are approximately perpendic-ular to one another, with a dihedral angle of 80.9 (5)° between them. The benzene ring is inclined to the mean planes of the two indole ring systems by 76.1 (3) and 78.3 (4)°. Weak intra-molecular C-H⋯π inter-actions affect the mol-ecular con...
