An extremely bulky xanthene bridged diamide ligand (NON = 4,5-bis(2,4,6-tricyclohexylanilido)-2,7-diethyl-9,9-dimethyl-xanthene) has been developed and used to prepare two monomeric diamido-calcium complexes [(NON)Ca(D)] (D = THF, = 2, 3; D = toluene, = 1, 4). Reduction of 4 with 5% w/w K/KI under an N atmosphere gave the first well-defined, hetero-bimetallic s-block complex of activated dinitrogen, [{K(NON)Ca}(μ-η:η-N)] 5, presumably a transient calcium(I) intermediate.
一种极其庞大的呫吨桥连二酰胺配体（NON = 4,5-双（2,4,6-三环己基苯胺基）-2,7-二乙基-9,9-二甲基-呫吨）已被开发出来，并用于制备两种单体二酰胺钙配合物[(NON)Ca(D)]（D = 四氢呋喃，= 2,3；D = 甲苯，= 1,4）。在氮气气氛下，用5% w/w的钾/碘化钾还原4，得到了第一个明确的、活化二氮的异双金属s区配合物[{K(NON)Ca}(μ-η:η-N₂)] 5，推测它是一种瞬态钙（I）中间体。
