Abstract

In the title compound, C22H29Cl3O13, the glucopyran ring exists in the chair conformation while the glucofuran ring adopts an envelope conformation. Intra­molecular C—H⋯O hydrogen bonds occur. In the crystal, adjacent mol­ecules are linked by weak inter

Abstract

The unit cell of the title compound, C7H6O4·H2O, features four independent formula units; the individual carb­oxy­lic acid mol­ecules themselves are nearly planar (r.m.s. deviations = 0.0189, 0.0334, 0.0356 and 0.0441 Å). Two independent mol­ecules each

Abstract

The title compound, C6H8N4O3·2H2O, which crystallized as a dihydrate, has two almost planar segments viz. the pyrimidine ring and the C—N—C(=O)—C group [maxmum deviations of 0.020 (2) and 0.014 (2) Å, respectively], with a dihedral an

Abstract

In the title compound, C24H21N3OS, the pyrazole ring makes dihedral angles of 5.40 (7) and 6.72 (8)° with the benzo[d]thiazole ring system and the benzene ring, respectively, and a dihedral angle of 85.72 (8)° with the meth­oxy-substituted benzene ring. In

Abstract

The non-H atoms of the title compound, C11H6BrFO3, are essentially coplanar (r.m.s. deviation for all non-H atoms = 0.074 Å). In the crystal, the molecules are linked by C—H⋯O and C—H⋯Br inter­actions.

Abstract

The title compound, [Ni(C13H15)2], shows a slightly distorted sandwich structure with two independent mol­ecules in the asymmetric unit. Both Ni atoms are located on crystallographic centres of inversion.

Abstract

In the mol­ecule of the title compound, C21H14N2O3, the tetra­hydro­benzo[h]quinoline fused-ring system is buckled owing to the ethyl­ene –CH2CH2– fragment, the benzene ring and the pyridine ring being twisted by 24.3 (1)°.

Abstract

In the monomeric dinuclear title complex, [CuSm(C20H22N2O4)(NO3)3], the four-coordinate CuII ion has a square-planar geometry involving two O atoms and two N atoms of the deprotonated Schiff base ligand. The SmIII</

Abstract

In the crystal structure of the title compound, C18H18O4, the full mol­ecule is generated by the application of an inversion centre. The mol­ecule is essentially planar, with an r.m.s. deviation of 0.017 (1) Å for all non-H atoms. The mol­ecules are linked through
