We report the synthesis and structures of 9,10,20,21-tetrahydro-5,14-(ethanooxyethano)dibenzo[e,q][1,4,10,13,7,16]tetraoxadiazacyclooctadecine-6,13-dione [systematic name: 8,11,21,24,29-pentaoxa-1,18-diazatetracyclo[16.8.5.0.0]hentriaconta-2,4,6,12(17),13,15-hexaene-19,26-dione CHNO, I], 6,7,9,10,12,13,20,21-octahydro-5,14-(ethanooxyethano)dibenzo[e,q][1,4,10,13,7,16]tetraoxadiazacyclooctadecine-23,27-dione (8,11,21,24,29-pentaoxa-1,18-diazatetracyclo[16.8.5.0.0]hentriaconta-2,4,6,12,14,16-hexaene-27,31-dione; CHNO, II), and 9,10,20,21-tetrahydro-5,14-(ethanooxyethanooxyethano)dibenzo[e,q][1,4,10,13,7,16]tetraoxadiazacyclooctadecine-6,13-dione [8,11,21,24,29,32-hexaoxa-1,18-diazatetracyclo[16.8.8.0.0]tetratriaconta-2,4,6,12(17),13,15-hexaene-19,26-dione; CHNO, III]. All three compounds are made up of two tertiary diamides and are composed of two 15-membered rings with NO donor sets and one 18-membered ring with an NO donor set (compounds I and II) or three 18-membered rings with NO donor sets (compound III). The solid-state structures of compounds I and II show little effects from the movement of the amide groups. However, compound III has a larger cavity and a different orientation of donor atoms in comparison to compounds I and II.
我们报告了 9,10,20,21-四氢-5,14-(乙氧乙氧基乙氧基)二苯并[e,q][1,4,10,13,7,16]六氧杂环十八烷-6,13-二酮 [系统命名：8,11,21,24,29-五氧-1,18-二氮杂三环[16.8.5.0.0]亨三嗪-2,4,6,12(17),13,15-六烯-19,26-二酮 CHNO，I]、6,7,9,10,12,13,20,21-八氢-5,14-(乙氧乙氧基乙氧基)二苯并[e,q][1,4,10,13,7,16]六氧杂环十八烷-23,27-二酮（8,11,21,24,29-五氧-1,18-二氮杂三环[16.8.5.0.0]亨三嗪-2,4,6,12,14,16-六烯-27,31-二酮；CHNO，II）和 9,10,20,21-四氢-5,14-(乙氧乙氧基)二苯并[e,q][1,4,10,13,7,16]六氧杂环十八烷-6,13-二酮[8,11,21,24,29,32-六氧-1,18-二氮杂三环[16.8.8.0.0]四聚体-2,4,6,12(17),13,15-六烯-19,26-二酮；CHNO，III]。所有三种化合物均由两个叔酰胺组成，由两个含 NO 给体的 15 元环和一个含 NO 给体的 18 元环（化合物 I 和 II）或三个含 NO 给体的 18 元环（化合物 III）组成。化合物 I 和 II 的固态结构显示酰胺基团的运动影响很小。然而，与化合物 I 和 II 相比，化合物 III 具有更大的空腔和给体原子的不同取向。
