  摘要：

  AbstractTreatment of an acetonitrile solution of CuCN with methylcycloarsoxane (CH3AsO)n at 110 °C affords the coordination polymer [CuCN{cyclo‐(CH3AsO)4}] (1), in which infinite CuCN zigzag chains are linked by μ‐As1, As3 cyclotetramers (CH3AsO)4 into an open 3‐D framework. Under similar solvothermal conditions, reaction of CuSCN with (CH3AsO)n in the presence of KSCN leads to metal‐mediated ring expansion of the cyclo‐arsoxane to yield the complex [{K[cyclo‐(CH3AsO)5]2}Cu(NCS)2] (2). This contains discrete [Cu(NCS‐κN)2{cyclo‐(CH3AsO)5κAs}2]— anions that bridge κ10O coordinated potassium cations into infinite chains. In contrast, the structure directing role of the [K(1, 7DT18C6)2]+ sandwich building units for the solvothermal product [{K(1, 7DT18C6)2}Cu6(CN)7] (3) (1, 7DT18C6 = 1, 7‐dithia‐18‐crown‐6) leads to formation of an open [{Cu6(CN)7}—] framework. Individual [K(1, 7DT18C6)2]+ moieties bridge Cu Atoms in a μ‐S1, S7 mode and are encapsulated within the large [Cu26(CN)28]2— cages of the cyanocuprate(I) network.
