The asymmetric unit of the title compound, (C(5)H(14)N(2))[ZnCl(4)], consists of a diprotonated 2-methyl-piperazine cation and a tetra-chloridozincate anion. The Zn(II) ion is in a slightly distorted tetra-hedral coordination environment. The six-membered piperazine ring adopts a chair conformation. The crystal structure is stabilized by inter-molecular N-H⋯Cl hydrogen bonds.

The title compound, (C10H21N3)[CuCl4], is composed of one 1-[2-(di-ethyl-aza-nium-yl)eth-yl]-3-methyl-imidazolium dication and a tetra-chlorido-cuprate(II) dianion.

Copper(I) thiocyanate (CuSCN) is an effective interlayer material for hole injection and transport in organic electronic devices but its solution processing has conventionally utilized undesirable di-n-alkyl sulfide solvents such as diethyl- (DES) dipropyl-sulfide (DPS). Herein, this paper reports on the use of N,N-dimethylformamide (DMF) 1-methyl-2-pyrrolidinone (NMP) alternative CuSCN interla...

Methylation study of the polysaccharides showed three methylated components namely-2,3,diO-methyl-D-mannose, 2,3,6-tri-O-methyl-D-mannose and 2,3,4,6-tetra-O-methyl-Dgalactose in the molar ratio of 1:2:1:. Thus, the polysaccharide consists of a main chain of D-mannanopyranose units and D-galactopyranose unit is present in the side chain.

In the title compound, [CdBr(2)(C(5)H(12)N(2)S)(2)], the Cd(II) atom lies on a twofold rotation axis. It exhibits a distorted tetra-hedral coordination environment defined by two S atoms of two tetra-methyl-thio-urea (tmtu) ligands and two bromide ions. The crystal structure is consolidated by C-H⋯N and C-H⋯S hydrogen bonds.

The title compound, C42H48O6, was obtained via formyl-ation of 25,26,27,28-tetra-propoxycalix[4]arene with dichloro-methyl methyl ether and tin tetra-chloride. It adopts a pinched cone conformation, which leads to an open cavity. The two opposite aromatic rings bearing formyl groups are almost parallel, making a dihedral angle of 29.1 (2)°. The other pair of opposite rings are close to being pe...
