Crystal structure and Hirshfeld surface analysis of a pyridiniminium bromide salt: 1-[2-(adamantan-1-yl)-2-oxoethyl]pyridin-4-iminium bromide

2018

The asymmetric unit of the title pyridiniminium halide salt comprise of one cation and one anion. In the crystal, mol­ecules are linked by N—H⋯Br and C—H⋯O hydrogen bonds, C—H⋯π inter­actions, and π–π inter­actions into layers. The inter­molecular inter­actions in the crystal structure are qu­anti­fied by Hirshfeld surface analysis.

Crystal structure of catena-poly[[[(2-ethoxypyrazine-κN)copper(I)]-di-μ2-cyanido] [copper(I)-μ2-cyanido]]

2019

The title compound, {[Cu(EtOpz)(CN)2][CuCN]}n, where EtOpz is 2-eth­oxy­pyrazine, is a two-dimensional polymeric copper complex with different coordination environments of the two CuI ions. One Cu atom is coordinated to the 2-eth­oxy­pyrazine mol­ecule and two bridging cyanide ligands, equally disordered over two sites. The second Cu atom is coordinated by two disordered over two sites bridging cyanide groups. Two copper–cyanide chains are connected through Cu⋯Cu contact.
