文摘
A new right angle-shaped ligand, 2,2'-bis(4-pyridyl)-9,9'-spirobifluorene (L), is designed and synthesized. Treatment of L with silver(I) ions leads to linear polymeric metal-organic frameworks, [Ag(L)2]+ (1), thatfeature square subunits. Single-crystal X-ray analysis reveals that [Ag(L)2]+ has a one-dimensional double-strandedpolymeric chain comprising square grids with cavity dimensions of ca. 8 Å × 8 Å. By 
- stacking of adjacentdouble-stranded chains, the structure is extended into a two-dimensional (2D) layer framework with a unique quasi-aperture (dimensions of ca. 14 Å × 8 Å). Each 2D layer is inclined and mutually interpenetrated, which gives riseto the three-dimensional interlocked network structure. Compound 1·(BF4)(CH3OH) crystallizes in the monoclinicsystem, space group C2/c, with chemical formula C71H49N4OBF4Ag, a = 25.709(1) Å, b = 14.4164(6) Å, c = 15.6865(7) Å, 
= 109.220(2)
, and Z = 4.
