Synthesis and crystal structure of [(2,4-C7H11)2LnCCC6H5]2 (Ln=Gd, Er)
摘要:
The reaction of (2,4-C7H11)(3)Ln (Ln=Gd, Er) with HC=CC6H5 in toluene leads to [(2,4-C7H11)(2) LnC=CC6H5](2), which crystallizes in the space group Pabc. The molecule shows the dimer structure, where two (2,4-C7H11)(2)Gd or Er units are connected by asymmetrical alkynide bridges. (C) 1999 Elsevier Science S.A. All rights reserved.
