文摘

The simple linear linking ligand diazabicyclo[2.2.2]octane (dabco) combines with silver(I) to form three-dimensional (3D) coordination polymers which have either a zeolitic mtn topology structure or a (10,3)-b ths network according to the counteranion used. The tetrahedral anions BF₄^{鈥?/sup> or ReO₄鈥?/sup> promote formation of [Ag(dabco)₂]路X, which has a 3D four-connected mtn framework of fused 512 and 64512 cages, and the material shows modest absorption of iodine. The bulky anion [Co(C₂B₉H₁₁)₂]鈭?/sup> and an excess of dabco promote formation of complex [Ag₂(dabco)₃(CH₃CN)₂]路2[Co(C₂B₉H₁₁)₂] with a three-connected (10,3)-b network, while use of 1 equiv of dabco gives a previously reported [Ag(dabco)]路[Co(C₂B₉H₁₁)₂], which has a one-dimensional coordination chain structure.}
