摘要:Five coordination compounds (CCs) of the formulas {[Ag(m-abn) _2]?NO _3} _n (1), {[Ag _2(m-abn) _6]?(ClO _4) _2} (2), {[Ag(o-abn) _2]?NO _3} _n (3), [Ag(o-abn) _2(NO _2)] _n (4), and {[Ag(o-abn) _2]?PF _6} _n (5) (m-abn = 3-aminobenzonitrile, and o-abn = 2-aminobenzonitrile) were synthesized and structurally characterized by element analysis, IR, powder X-ray diffraction, and X-ray single-crystal diffraction. Structural analysis reveals that aminobenzonitrile acts as bidentate μ _2-N,N′ or monodentate μ _1-N ligands in 1-5. Complex 1 is a 1D chain comprised of C _2-symmetric [Ag(m-abn)] _2 14-membered rings. The uncoordinated NO _3 ~- anions interact with the 1D chain to form a resulting 2D supramolecular sheet through N-O???N hydrogen bond. Complex 2 is a discrete binuclear Ag(I) CC incorporating concurrent bidentate μ _2-N,N′ and monodentate μ _1-N m-abn ligands. The variation of anions from NO _3 ~- to ClO _4 ~- results in the dimensionalities of 1 and 2 decreasing from 1D to 0D. When using o-abn, complexes 3-5 are obtained as 1D chain with C _2-symmetric [Ag(o-abn)] _2 12-membered rings, 2D sheet with coordinated μ _2-η ~1:η ~2 NO _2 ~- anions, and 1D chain with centrosymmetric [Ag(o-abn)] _2 12-membered rings, respectively. Supramolecular interactions such as hydrogen bonding and π???π stacking are also proven effective in shaping the dimensionalities of the solid state structures of 1-5. Our results demonstrate that the anions are driving forces for the selection of different structures. Moreover, results about emissive behaviors and thermal stabilities of them are discussed.
