The ternary inter-metallic title phase, distrontium cadmium diplatinum, was prepared from stoichiometric amounts of the elements at 1123 K for one day. The crystal structure adopts the ortho-rhom-bic Ca2GaCu2 structure type in space group Immm. Its main features are characterized by linear (Pt-Pt⋯Pt-Pt) n chains that are aligned along [010] and condensed through cadmium atoms forming Cd-centred...

In the title mol-ecule, C(17)H(13)NO(2), the allyl group is almost perpendicular to the carbazole mean plane, with a dihedral angle of 89.0 (2)°. In the crystal, nonclassical C-H⋯O hydrogen bonds link the mol-ecules into corrugated sheets parallel to the bc plane. Weak inter-molecular π-π inter-actions are observed between the benzene rings [centroid-centroid distance = 3.874 (4) Å] from neighb...

In the title compound, [Zn(C(18)H(39)N(3)O(3))](NO(3))(2)·H(2)O, the coordination geometry around the central Zn(II) atom is distorted octa-hedral. The hydroxyl groups in the macrocyclic ligand and water mol-ecules are engaged in O-H⋯O hydrogen bonding, which forms two-dimensional corrugated sheets comprising 34-membered rings. Neighbouring sheets are connected by C-H⋯O inter-actions.

In the title compound, {[Co(C(8)H(4)O(4))(C(10)H(8)N(4))]·2C(3)H(7)NO·0.5H(2)O}(n), the Co(II) atom is six-coordinated by four O atoms from two benzene-1,4-dicarboxyl-ate (H(2)bdc(2-)) groups and two N atoms from two 4,4'-azopyridine (4,4'-azpy, or di-4-pyridyldiazene) ligands, leading to a distorted octa-hedral geometry. The structure consists of two-dimensional corrugated sheets with a 4(4) t...

The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than other systems because of adequate stiffness, ductility, and more energy absorption. The system of steel shear wall with corrugated sheets has been offered as an innovative sys...

In the title compound, C(16)H(16)N(2)O(5)·CH(4)O, the two benzene rings in the Schiff base mol-ecule form a dihedral angle of 17.1 (1)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the components into corrugated sheets parallel to the (101) plane.

In the title compound, C15H13N3O, the pyrrolyl and phenyl rings make dihedral angles of 58.99 (5) and 34.95 (5)°, respectively, with the central pyrazole ring. In the crystal, weak, pairwise C-H⋯O inter-actions across centers of symmetry form dimers, which are further associated into corrugated sheets running approximately parallel to (100) via weak C-H⋯N inter-actions.
