摘要: Abstract The organolithium etherate complexes [Li(Et 2 O) (CPh 3 )] ( 1 ) and [{Li(Et O)(2,4,6-(CHMe C 6 H )} ] have been crystallized from their ether solutions structurally characterized by X-ray crystallography. complex has the rare mononuclear structure, with lithium coordinated to two ethers at least three carbon atoms of CPh group; it thus offers an interesting comparison structure [Li(12-crown-4) ][CPh ], which contains a free [CPh − ion. is dimeric, features bridging between 2,4,6-(CHMe (Trip) groups. are three-coordinate, being bonded diethyl in addition atoms. A significant feature this asymmetric nature bridging, distortion angles distances surrounding apparent. This suggestive weak association due large size Trip group. These structures represent additions small number known involving compounds solvated commonly used monodentate solvents.
