Organometallic Compounds of the Lanthanoides. LXVI. Synthesis and X‐ray crystal structure of [O(CH₂CH₂C₅H₄)₂Y(μ‐OH]₂ and (MeC₅H₄)₃Ho(H₂O), two unusual products of the hydrolysis of organolanthanoide compounds

Abstract

Abstract The partial hydrolysis of [O(CH 2 CH 2 C 5 H 4 ) 2 ]Y(C 5 H 4 CH 3 ) 1 , [O(CH 2 CH 2 C 5 H 4 ) 2 ]Y(C 5 H 5 ) 3 , and [O(CH 2 CH 2 C 5 H 4 ) 2 ]Ho(C 5 H 4 CH 3 ) 5 results in the formation of [O(CH 2 CH 2 CH 2 C 5 H 4 ) 2 Y(μ‐OH) 2 ] 2 2 , (C 5 H 5 ) 3 Y(OH 2 ) 9 and (MeC 5 H 4 ) 3 Ho(OH 2 ) 11 . The new compounds have been characterized by elemental analyses, IR and NMR spectra. The X‐ray structural analyses shows 2 to be monoclinic, space group P2 1 /n with a = 1146.0(3), b= 1046.6(3), c = 1514.9(3) pm, β = 94.83(2)°. The molecular structure shows bridging hydroxyl groups with a mean distance YO = 223.8(3) pm. 11 crystallizes in the cubic space group 1 4 3d with a = 1847.9(3)pm with Z = 16 molecules per unit cell. The molecules posses symmetry C 3 ‐3, the coordination is trigonal pyramidal with three methylcyclopentadienyl anions and one water molecule as ligands. The distance HoO is 231 pm.
