research communications (GM)Structure of tetrakis(μ-decanoato-κ2O,O′)bis[(4-methylpyridine-κN)copper(II)], a dimeric copper(II) complex
The 4-methylpyridine (4-Mepy) based dimeric copper(II) carboxylate complex [Cu2(C10H19O2)4(C6H7N)2] or [Cu2(μ-O2CC9H19)4(4-Mepy)2] crystallizes with triclinic (P
) symmetry. The two CuII ions exhibit a distorted square-pyramidal environment and are connected into a centrosymmetric paddle-wheel dinuclear cluster [Cu⋯Cu = 2.6472 (8) Å] via four bridging carboxylate ligands arranged in the syn–syn coordination mode. The apical positions around the paddle-wheel copper centers are occupied by the N atoms of the 4-methylpyridine ligands. Parts of the decanoate chains are disordered with occupancy ratios of 0.817 (9):0.183 (9) and 0.65 (5):0.35 (5).
research communications (GO)Fifteen 4-(2-methoxyphenyl)piperazin-1-ium salts containing organic anions: supramolecular assembly in zero, one, two and three dimensions
Fifteen 4-(2-methoxyphenyl)piperazin-1-ium salts with organic anions exhibit a range of hydrogen-bonded supramolecular assemblies in the form of finite aggregates, a chain of rings, ribbons, sheets and three-dimensional networks.
