The hydrothermal reaction of Na 2MoO 4, Ag(CH 3CO 2), tetra-2-pyridylpyrazine (tpyprz), HF and water at 170°C for 48 h yields [{Ag 4(tpyprz) 2(H 2O)}Mo 8O 26] (1) as colorless plates. The structure of 1 is a two-dimensional network, constructed from {Ag 4(tpyprz) 2(H 2O)} 4n+ n chains linked through ζ-Mo8O264- clusters. The chains exhibit three distinct Ag(I) environments: a four coordinate {AgN 4} site, a three coordinate {AgN 2O aqua} site, and four coordinate {AgN 3O oxo} site which links to the molybdate cluster. Each cluster is connected by bridging oxo-groups to two silver/tpyprz chains to form the network architecture. Crystal data: C 24H 17Ag 2Mo 4N 6O 13.5, fw 1204.94, orthorhombic Pccn, a=20.8234(9) Å, b=14.5076(6) Å, c=20.3537(9) Å, V=6148.9(5) Å3, Z=8, Dcalc=2.603 g cm-3. Graphical Abstract. Hydrothermal reaction conditions provide a two-dimensional organic-inorganic hybrid material [{Ag 4(tpyprz) 2(H 2O)}Mo 8O 26], constructed from {Ag 4(tpyprz) 2(H 2O)} 4n+ n chains and ζ-Mo8O264- clusters.
