title: Bis(μ-bis-{[4-(2-pyrid-yl)pyrimidin-2-yl]sulfan-yl}methane)-disilver(I) bis-(perchlorate).
abstract: In the macrocyclic centrosymmetric dinuclear complex, [Ag(2)(C(19)H(14)N(6)S(2))(2)](ClO(4))(2), the Ag(I) atom, bis-{[4-(2-pyrid-yl)pyrimidin-2-yl]sulfan-yl}methane (2-bppt) ligand and perchlorate anion each lie on a twofold rotation axis. The 2-bppt ligand chelates two four-coordinated Ag(I) 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 mol-ecules are linked by π-π inter-actions between the pyridine and pyrimidine rings [centroid-centroid distance = 3.663 (8) Å].
