Syntheses and Crystal Structures of Three Polymeric Silver(I) Terephthalate Complexes with Organic N‐Donor Ligands: [Ag(pren)] 2 (tp)·2H 2 O, [Ag(en)][Ag( μ 2 ‐tp)]·H 2 O, and [Ag 2 ( μ 4 ‐tp)(apy) 2 ]

Three polymeric silver(I) complexes with terephthalate anions as counterions or ligands, [Ag(pren)] 2 (tp)·2H 2 O ( 1 ), [Ag(en)][Ag( μ 2 ‐tp)]·H 2 O ( 2 ), and [Ag 2 ( μ 4 ‐tp)(apy) 2 ] ( 3 ) (where pren = 1, 2‐propylenediamine, tp =terephthalate dianion, en = ethylenediamine, and apy = 2‐aminopyridine) were synthesized and characterized by X‐ray single crystal analysis and infrared spectroscopy. 1 crystallizes in the monoclinic space group P2 1 1 /c with a = 11.3221(5), b = 7.1522(3), c = 14.8128(5)Å, V = 1015.77(7)Å 3 , β = 122.132(2), and Z = 2. 2 crystallizes in the orthorhombic space group Pnma with a = 9.6144(6), b = 11.3465(7), c = 11.4810(7)Å, V = 1252.5(1)Å 3 , and Z = 4. 3 crystallizes in the monoclinic space group P2 1 /n with a = 8.2003(5), b = 5.8869(4), c = 18.3769(11)Å, β = 92.593(1), V = 886.2(1)Å 3 , and Z = 4. Terephthalate dianions are not coordinated to the metal atoms in 1 , but act as a μ 2 ‐bridging ligand in 2 and as a μ 4 ‐bridging ligand in 3 .
