The reaction of AgPF6 in methanol with 1,3-dibromo-2,2-bis[(isonicotinoyloxy)methyl]propane (L) in dichloromethane affords an acentric diamondoid 3D silver(I) coordination polymer, [Ag(L)2]n(PF6)n with 2-fold interpenetration with alternating perpendicular “right-handed” and “left-handed” helical channel motifs induced by the bent ligand.
