Isolation and crystal structure of a six coordinate yttrium trichloride complex of .epsilon.-caprolactone, YCl3(C6H10O2)3

Abstract

The first crystallographically characterized caprolactone complex of yttrium has been obtained by crystallizing YCl[sub 3] from [epsilon]-caprolactone. The caprolactone ligands generate a six-coordinate complex, YCl[sub 3](C[sub 6]H[sub 10]O[sub 2])[sub 3], rather than a coordinate structure as is commonly found by solvated yttrium and lanthanide trihalide complexes. The caprolactone ligands are bound only through the carbonyl oxygen atoms. 20 refs., 1 fig., 1 tab.
