New Ag(I) coordination polymers of 2,6-pyridine-dicarboxamide: In situ ligand formation and a unique secondary building unit

Coordination polymers of 1,8-bis(2-methylthioethoxy)anthraquinone and 1,5-bis(2-methylthioethoxy)anthraquinone with Ag(I): Synthesis and X-ray crystallography

“…4 and selected bond lengths and bond angles are given in Table 3. (14) Å, is compatible with the earlier report [14]. The crystallization solvent, CH 3 CN, has occupied one of the coordination sites of Ag(I) and the Ag1-N2 bond length is 2.4452(19) Å.…”

“…Three Ag-S bonds in 3 are of unequal lengths, Ag-S2, 2.490 (18) Å; Ag-S1, 2.532 (17) Å and Ag-S1 (from adjacent molecule), 2.651 (15) Å. The intraannular carbonyl group's bond length [C14-O4; 1.250 (6) Å], bonded to Ag(I) is longer than the outer carbonyl group [C7-O1; 1.228 (7) Å] and Ag-O4, 2.350 (4) Å bond length is similar to an earlier report [14]. The S1-Ag-O4 bite angle is 109.82 (10)°, a typical value for tetrahedral geometry, whereas, the other bite angle S2-Ag-O4 is slightly deviated [118.69 (10)°] from the expected value.…”

Facile synthesis of silver alkynide cluster and coordination polymers using picolinic acid as a co-ligand

“…PPh 3 . 18 On the other hand, pyridine dicarboxylates have led to an assembly of the homoleptic structural motif into 2D-layered structures via additional hydrogen bonding (2), 19 while in other cases carboxylate oxygen atoms also engage in bridging coordination modes yielding interesting Ag 2 O 2 -cyclic motifs (3). 20,21 To the best of our knowledge, there is only one example in which alkynide coordination is combined with a pyridine carboxylate motif.…”

Supramolecular assembly of a dinuclear Ag(I) complex with discreet Ag2S2 centers

“…Silver(I) compounds with multidentate ligands have received much attention due to their ability to self-assemble as coordination polymers through non-covalent interactions [1][2][3][4][5][6][7][8][9]. The ability of Ag(I) to adopt numerous coordination environments coupled with ligands that incorporate hydrogen-bond donors/acceptors and/or p-p interactions provides an avenue for the formation of a collection of extended network solids.…”

“…Compound 1 crystallizes in the orthorhombic space group Fdd2 as colorless plates upon slow evaporation of acetonitrile solutions. 1 As shown in Fig. 1 (top), the asymmetric unit contains half of the molecule with the remaining atoms generated by a C 2 rotation about an axis located at sulfur.…”
