The title compound, C(13)H(16)O, comprises two fused five-membered rings. Each ring has an envelope conformation, with the ether O atom in the furan-ose ring, and the CMe(2) atom in the acetonide ring as the flap atoms. In the crystal, centrosymmetrically related mol-ecules associate via hydr-oxy-ether O-H⋯O hydrogen bonds and the resulting dimers are linked into a supra-molecular chain with a ...

In the crystal structure of the title compound, C(7)H(6)BFO(2), a broad-spectrum anti-fungal drug (AN2690), the planar [maximum deviation 0.035 (1) Å] mol-ecules form centrosymmetric R(2) (2)(8) dimers via strong O-H⋯O hydrogen bonds. The dimers are arranged into layers by weak inter-molecular C-H⋯O and C-H⋯F hydrogen bonds. The symmetry of this two-dimensional supra-molecular assembly can be d...

The title mol-ecule, C(15)H(16)N(2)O(3)S, has a twisted U-shaped conformation. The twist occurs in the central C-S(=O)(2)N(H)-C unit with the C-S-N-C torsion angle being -58.38 (14)°. The benzene rings lie to the same side of the mol-ecule and form a dihedral angle of 67.03 (10)°. The crystal packing features N-H⋯O hydrogen bonding, which leads to supra-molecular chains with a tubular topology ...

In the title compound, C(15)H(16)N(2)S(2), the central C(2)N(2)S(2) unit is essentially planar (r.m.s. deviation = 0.047 Å) and forms dihedral angles of 68.26 (4) and 65.99 (4)° with the phenyl and benzene rings, respectively, indicating a twisted mol-ecule. Supra-molecular chains with a step topology and propagating along [100] feature in the crystal packing, mediated through N-H⋯S hydrogen bo...

Topology is an important and major area of mathematics and it can give many relationships between other scientific areas and mathematical models. Recently, many scientists have studied and improved the soft set theory, which is initiated by Molodtsov [27] and easily applied to many problems having uncertainties from social life. The main purpose of this paper, is to introduce more properties of...

In the crystal structure of the title complex, [Cu(C(6)H(4)N(5))(2)(CH(3)OH)(2)](n), the Cu(II) cation lies on an inversion center and is coordinated by four 5-(3-pyrid-yl)tetra-zolate anions and two methanol mol-ecules in an elongated distorted CuN(4)O(2) octa-hedral geometry. Each 5-(3-pyrid-yl)tetra-zolate anion bridges two Cu(II) cations, forming a two-dimensional polymeric complex with (4,...

In the title compound, C17H25N3O2S, the terminal and central amide groups are, respectively, twisted and coplanar with the attached benzene ring [O-C-C-C torsion angles = 22.7 (3) and 5.4 (3)°]. In the central part of the mol-ecule, the amide and thio-amide residues are approximately perpendicular [C-N-C-S torsion angle = -104.98 (18)°]. Supra-molecular layers with a zigzag topology are formed ...

In the title compound, [Zn(C(48)H(24)N(8))], the coordination environment of the Zn(2+) ion (site symmetry [Formula: see text]) is octa-hedral, with four indole N atoms forming the equatorial plane and the axial positions being occupied by N atoms from the cyanide groups of neighbouring molecules. In the crystal, adjacent mol-ecules are assembled into a two-dimensional supra-molecular framework...

The organic mol-ecule in the title monohydrate, C(6)N(6)O(5)·H(2)O, presents an almost planar configuration, the greatest deviation from the least-squares plane through the atoms being 0.061 (1) Å for the O atom within the seven-membered ring. Each water H atom is bifurcated, one forming two O-H⋯N hydrogen bonds and the other forming O-H⋯N,O hydrogen bonds. The result of the hydrogen bonding is...

In the title one-dimensional coordination polymer, [Zn(C(14)H(8)O(5))(C(12)H(8)N(2))](n), the Zn(II) ion is in a distorted octa-hedral coordination geometry with four O atoms from two carboxyl-ate groups in bidentate chelating modes and two N atoms from a 1,10-phenanthroline ligand. The two terminal carboxyl-ate groups bind the Zn(II) ions, leading to a chain along the c axis. Adjacent chains a...
