Three-Dimensional Silver-dabco\nCoordination Polymers\nwith Zeolitic or Three-Connected Topology

Abstract

The simple linear linking ligand\ndiazabicyclo­[2.2.2]­octane\n(dabco) combines with silver­(I) to form three-dimensional (3D) coordination\npolymers which have either a zeolitic <b>mtn</b> topology structure\nor a (10,3)-b <b>ths</b> network according to the counteranion\nused. The tetrahedral anions BF₄^– or\nReO₄^– promote formation of [Ag­(dabco)₂]·X, which has a 3D four-connected <b>mtn</b> framework\nof fused 5¹² and 6⁴5¹² cages, and\nthe material shows modest absorption of iodine. The bulky anion [Co­(C₂B₉H₁₁)₂]⁻ and an excess of dabco promote formation of complex [Ag₂(dabco)₃­(CH₃CN)₂]­·2­[Co­(C₂B₉H₁₁)₂] with a three-connected\n(10,3)-b network, while use of 1 equiv of dabco gives a previously\nreported [Ag­(dabco)]­·[Co­(C₂B₉H₁₁)₂], which has a one-dimensional coordination\nchain structure.
