In the resulting three‐dimensional coordination polymer, the ring centres represent the nodes of a distorted diamondoid network, whereby the high packing efficiency prevents the interpenetration of networks that is frequently observed in diamondoid solids. The primary N

coordination of the cation corresponds to a distorted tetrahedron with bond angles in the range 103.62(3)–118.57(3)°; including the short Ag···Ag contact and four secondary silver‐oxygen contacts at distances of 300.18(13) pm (2×) and 333.10(13) pm (2×), the coordination number is increased to nine. |
