    Description / Table of Contents: Tetramethylcyclotetraarsoxan-verbrückte Kupfer(I)-Halogenide mit porösen Schicht- und Raumnetz-Strukturen ∞2[CuX{cyclo-(MeAsO)4}] (X=Cl, Br, I) und ∞3[Cu3X3{cyclo-(MeAsO)4}2] (X=Cl, Br)Offene Schicht- und Raumnetzstrukturen von ∞2[CuX{cyclo-(MeAsO)4}] (X=Cl, Br, I) 1-3 und ∞3[Cu3X3{cyclo-(MeAsO)4}2] (X=Cl, Br) 4 und 5 können durch Selbstorganisation aus CuX und Methylcycloarsoxan (MeAsO)n in Acetonitril erhalten werden. 1-3 bilden 44-Netze, in denen (CuX)2-Einheiten durch μ-KAs1 : 2 KAs3 - koordinierte (MeAsO)4-Liganden zu großen 28-zähligen Ringen verbunden sind. Im Gegensatz dazu sind parallel angeordnete ∞1[CuX]-Ketten in 4 und 5 durch μ4-K4As-koordinierte (MeAsO)4-Gruppen zu Schichten verbunden, die durch μ-1 kAs1 : 2 kAs3-Verbrückung mit (MeAsO)4-Cyclotetrameren zur Bildung einer porösen Raumnetzstruktur führen. 1-5 wurden mittels Röntgenstrukturanalyse charakterisiert.
    Notes: Open sheet and framework structures ∞2[CuX{cyclo-(MeAsO)4}] (X=Cl, Br, I) 1-3 and ∞3[Cu3X3{cyclo-(MeAsO)4}2] (X=Cl, Br) 4 and 5 may be prepared by self-assembly from CuX and methylcycloarsoxane (MeAsO)n in acetonitrile solution. 1-3 exhibit 44 nets in which (CuX)2 units are connected through μ-1 KAs1 : 2 KAs3 coordinated (MeAsO)4 ligands into large 28-membered rings. In contrast, adjacent ∞1[CuX] chains in 4 and 5 are connected into sheets by μ4-K4 As coordinated (MeAsO)4 building blocks, with μ-1 KAs1 : 2 KAs3 bridging of these layers by independent (MeAsO)4 cyclotetramers leading to the generation of a porous framework structure. 1-5 were characterised by X-ray structural analysis.
