The title compound, C28H33N2S2P, adopts the thione tautomeric form, as supported by the C-S distance [1.6744 (18) Å]. The Schiff base exhibits an E conformation about the C=N bond but a Z conformation about the C-N bond. The terminal chain is disordered over two sets of sites with an occupancy ratio of 0.732 (3):0.268 (3). In the crystal, pairs of N-N-H hydrogen bonds between the thione groups ...

The title Schiff base compound, C(22)H(28)N(2)O(4), lies across a crystallographic inversion centre and adopts an E configuration with respect to the C=N bond. Pairs of weak inter-molecular C-H⋯O inter-actions link neighbouring mol-ecules into dimers with an R(2) (2)(28) ring motif. The crystal structure is stabilized by inter-molecular C-H⋯π inter-actions. An intramolecular O-H⋯N hydrogen bond...

In the title compound, C(13)H(9)Cl(2)NO, the meta-Cl atom in the benzoyl ring is positioned anti to the C=O bond, while the ortho-Cl atom in the aniline ring is positioned syn to the N-H bond. The two aromatic rings are almost coplanar, making a dihedral angle of 4.73 (5)°. The crystal structure is stabilized by N-H⋯O hydrogen bonds, which link the mol-ecules into chains along the b axis.

The title compound, C(8)H(8)N(2)O(4), is almost planar (r.m.s. deviation = 0.037 Å) and an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Inter-molecular N-H⋯O hydrogen bonds (involving the same H atom that forms the intra-molecular hydrogen bond) link the dimers into infinite sheet...

In the title mol-ecule, C20H17F2NO, which adopts an E conformation with respect to the imine C=N double bond, the mean planes of the naphthalene ring system and the difluoro-phenyl ring form a dihedral angle of 85.82 (7)°. An intra-molecular C-H⋯N hydrogen bond occurs. In the crystal, weak C-H⋯F hydrogen bonds link the mol-ecules into zigzag chains along [010].

My paper ®rst considers the relationship between nonaccounting information and traditional hospital ®nancial ratios. I found that nonaccounting information represents separate characteristics of hospital ®nancial performance. Second, the link between factors produced in the ®rst stage of the analysis and one dimension of hospital ®nancial performance, creditworthiness, is assessed. Bond ratings...

In the title compound, [Fe(C(5)H(5))(C(13)H(9)N(2))], the dihedral angle between the substituted cyclo-penta-dienyl plane and the plane of the pyridine ring is 8.43 (14)°. The double bond adopts a Z configuration. In the crystal structure, weak C-H⋯N inter-actions link the molecules into a zigzag chain. A weak intramolecular C-H⋯N hydrogen bond is also present.

In the mol-ecular structure of the title compound, C(14)H(12)ClNO, the meta-Cl atom in the benzoyl ring is positioned anti to the C=O bond, while the ortho-methyl group in the aniline ring is positioned syn to the N-H bond. The two benzene rings are nearly coplanar [dihedral angle = 3.48 (5)°]. The crystal structure is stabilized by N-H⋯O hydrogen bonds, which link the mol-ecules into chains al...

The title mol-ecule, C(20)H(21)NO(6), adopts a keto-amine tautomeric form. An intra-molecular N-H⋯O hydrogen bond, classified as a resonanse-assisted hydrogen bond, influences the mol-ecular conformation; the two benzene rings form a dihedral angle of 24.6 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains propagating along [001].

In the title compound, C14H9Cl2N3O4·C3H7NO, the hydrazone mol-ecule adopts an E conformation with respect to azomethine bond, and the dihedral angle between the two aromatic rings [8.96 (11)°] shows that the rings are almost co-planar. The planar conformation of the mol-ecule is stabilized by the intra-molecular O-H⋯N hydrogen bond involving the OH group and azomethine N atom. The azomethine an...
