N 2,N 2′-Bis(2-hydroxybenzylidene)-2,2′-bipyridyl-3,3′-dicarbohydrazide
In the title compound, C(26)H(20)N(6)O(4), the two aroylhydrazone side groups exist as diastereomeres, both in the keto form in the crystal structure. The aroylhydrazone units support the mol-ecular conformation through an intra-molecular N-H⋯O hydrogen bond. Two mol-ecules are connected into a centrosymmetric dimer by inter-molecular N-H⋯N hydrogen bonds. These dimers are connected into chains...
متن کاملMultiband superconductivity in BiS2-based layered compounds.
A mean-field treatment is presented of a square lattice two-orbital-model for [Formula: see text] taking into account intra- and inter-orbital superconductivity. A rich phase diagram involving both types of superconductivity is presented as a function of the ratio between the couplings of electrons in the same and different orbitals ([Formula: see text]) and electron doping x. With the help of ...
متن کاملN′-(3-Ethoxy-2-hydroxybenzylidene)benzenesulfonohydrazide
There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(16)N(2)O(4)S, both of which are stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds lead to [101] chains of mol-ecules in the crystal structure.
متن کاملN 2,N 2′-Bis(2,2-dimethylpropanoyl)benzene-1,3-dicarbohydrazide
In the mol-ecular structure of the title hydrazide derivative, C(18)H(26)N(4)O(4), the conformations of the two units of 2-(2,2-dimethyl-1-oxoprop-yl)hydrazide substituents are not planar; these two units are attached axially to the benzene ring with C(ortho)-C-C(=O)-N torsion angles of 28.1 (2) and 31.0 (2)° [where C(ortho) is the C atom at position 4 of the benzene ring relative to the substi...
متن کاملLong-term outcome after surgery for pulmonary stenosis (a longitudinal study of 22-33 years).
AIMS Long-term (>20 years) survival and clinical outcome are only partly documented in patients who underwent surgical repair for isolated pulmonary stenosis. Yet, such data are of critical importance for the future perspectives, medical care, employability, and insurability of these patients. METHODS AND RESULTS Ninety consecutive patients underwent surgery for pulmonary stenosis between 196...
