Abstract: | The hydrothermal reaction of Na2MoO4, Ag(CH3CO2), tetra-2-pyridylpyrazine (tpyprz), HF and water at 170 °C for 48 h yields Ag4(tpyprz)2(H2O) Mo8O26] (1) as colorless plates. The structure of 1 is a two-dimensional network, constructed from Ag4(tpyprz)2(H2O) 4n+n chains linked through ζ- clusters. The chains exhibit three distinct Ag(I) environments: a four coordinate AgN4 site, a three coordinate AgN2Oaqua site, and four coordinate AgN3Ooxo 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: C24H17Ag2Mo4N6O13.5, 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. |
