Coordination Chemistry of Anticrowns. Interaction of the Perfluorinated Three-Mercury Anticrown (o-C6F4Hg)3 with Azacrowns

The interaction of the three-mercury anticrown (o-C6F4Hg)3 (1) with various azacrowns such as 2,9,16,23-tetra-tert-butylphthalocyanine (TBPC), octaazapentacyclooctacosane (OAOC), 1,4,8,11-tetraazacyclotetradecane (cyclam), and N,N,N-trimethyl-1,3,5-triazacyclohexane (TACH) has been studied. It has been shown that the reaction of 1 with TBPC in CH2Cl2 at 20 °C affords 1:1 complex {[(o-C6F4Hg)3](TBPC)} (2) according to elemental analysis, and the interaction of 1 with OAOC·0.5H2O in ether results in the formation of complex {[(o-C6F4Hg)3]2(OAOC)(H2O)2} (3). The molecules of azacrown and water in 3 are located between the parallel planes of two mercuramacrocycles strongly laterally shifted relative to one another and are bonded to them through Hg–N and Hg–O secondary interactions. An especially interesting complex, [(CH2)10(NH2)2(NH)2]{[(o-C6F4Hg)3]2Cl2} (4), has been obtained by the reaction of 1 with cyclam [(CH2)10(NH)4] in CH2Cl2 at 20 °C. The complex has a structure of a double-decker sandwich wherein t...
