gave [M(heterocrown)(MeCN)2][BArF]2 for M = Mg, Ca or Sr, whilst the larger Ba forms [Ba(heterocrown)(acacH)(MeCN)][BArF]2. The complexes have been characterised by microanalysis, IR, 1H and 13C1H} NMR spectroscopy. X-ray crystal structures are reported for [Ca([18]aneO2S4)(MeCN)2][BArF]2, [Ca([18]aneO4Se2)(MeCN)2][BArF]2, [Sr([18]aneO4S2)(MeCN)2][BArF]2, and [Sr([18]aneO4Se2)(MeCN)2][BArF]2 which
描述了一种从金属乙腈配合物与弱配位[BAr F ] -阴离子到Mg,Ca,Sr和Ba与18元环O 4 S 2,O 4 Se 2和O 2 S 4供体大环的阳离子配合物的新途径。使用的前体是[M(MeCN)x ] [BAr F ] 2(M = Mg,x = 6; M = Ca,x = 8)和[M'(acacH)(MeCN)5 ] [BAr F ] 2(M'= Sr或Ba)。这些与杂皇冠[18] aneO 4 S 2的反应(1,4,10,13-四氧杂-7,16-二硫代环十八烷),[18] aneO 4 Se 2(1,4,10,13-四氧杂-7,16-二硒代环十八烷)或[18] aneO 2 S 4(1,10-dioxa-4,7,13,16-tetrathiacyclooctadecane)在无水CH 2 Cl 2溶液中得到[M(杂居](MeCN)2 ] [BAr F ] 2,其中M = Mg,C
