1-[2-(Pyrazin-2-ylsulfanyl)ethyl]pyrazine-2(1H)-thione [PDF]
The title multifunctional twisted organic ligand, C(10)H(10)N(4)S(2), contains a short C=S bond [1.671 (2) Å]. The dihedral angle between the two pyrazine rings is 39.83 (6)°. In the crystal, inter-molecular C-H⋯N and C-H⋯S hydrogen bonds result in the formation of a supra-molecular network.

Predicting Atomic Charges in MOFs by Topological Charge Equilibration
An atomic charge prediction method is presented that is able to accurately reproduce ab‐initio‐derived reference charges for a large number of metal–organic frameworks. Based on a topological charge equilibration scheme, static charges that fulfill overall neutrality are quickly generated.

A gram‐scale supply of bulbiferamide A, which features a rare N‐acylindole linkage and possesses potent inhibitory activity against Trypanosoma cruzi epimastigotes (IC50 = 4.1 µM)—the causative parasite of Chagas disease—was successfully achieved. Moreover, the cyclization strategy developed in this study facilitated the synthesis of noncanonical ...

μ-Pyrazine-bis[tetraaquacadmium(II)] μ-pyrazine-bis[tetraacetatocadmium(II)] [PDF]
In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes.

N,N′-Bis(pyrazin-2-ylmethyl)pyrazine-2,3-dicarboxamide [PDF]
The title compound, C16H14N8O2, was prepared by a condensation reaction between the dimethyl ester of pyrazine-2,3-dicarboxylic acid and an excess of 2-(aminomethyl)pyrazine. The molecule is approximately V-shaped with the central pyrazine ring joined through amide linkages to two pyrazin-2-ylmethyl substituents. In the crystal, molecules are linked by
