Bis(μ-bis{[4-(2-pyridyl)pyrimidin-2-yl]sulfanyl}methane)disilver(I) bis(perchlorate)
Abstract
In the macrocyclic centrosymmetric dinuclear complex, [Ag2(C19H14N6S2)2](ClO4)2, the AgI atom, bis{[4-(2-pyridyl)pyrimidin-2-yl]sulfanyl}methane (2-bppt) ligand and perchlorate anion each lie on a twofold rotation axis. The 2-bppt ligand chelates two four-coordinated AgI atoms through its two bipyridine-like arms. The O atoms of the perchlorate anion are disordered each over two positions of equal occupancy. Adjacent complex molecules are linked by π–π interactions between the pyridine and pyrimidine rings [centroid–centroid distance = 3.663 (8) Å].
