Reaction of Cu I , tricyanomethanide (tcm − , C(CN) 3 − ) and L=either hexamethylenetetramine (hmt), 4,4′‐bipyridine (bipy) or 1,2‐bis(4‐pyridyl)ethene (bpe) gives crystals of [Cu(tcm)(hmt)] ( 1 ), [Cu(tcm)(bipy)] ( 2 ) and [Cu(tcm)(bpe)]⋅0.25 bpe⋅0.5 MeCN ( 3 ), respectively. Crystal structure analysis shows 1 ‐ 3 all contain closely related puckered (4,4) sheets composed of tetrahedral Cu I ions bridged by 2‐connecting tcm − and L. The crystal packing, however, varies markedly with L. In 1 the sheets interdigitate in pairs. In 2 the sheets participate in parallel interpenetration in pairs. In 3 guest bpe and MeCN molecules are intercalated in channels formed by the stacking of the sheets.
