With the facile displacement being utilized of thf from Yb(pin)2(thf)4 (pin = 2-phenylindol-1-yl, thf = tetrahydrofuran) in toluene solution, the complexes Yb(pin)2(dme)2 (dme = 1,2-dimethoxyethane), Yb(pin)2(tmen) (tmen = N,N,N',N'-tetramethylethane-1,2-diamine) and Yb(pin)2(diglyme)(thf) (diglyme = bis(2-methoxyethyl) ether) have been prepared from the respective ligands and Yb(pin)2(thf)4.Yb(pin)2(diglyme)(thf) 1/c, a 15.35(1), b 16.179(5), c 14.45(2) Angstroem, β 107.51(8) deg, Z 4, R 0.044 for 2956 (I > 3?(I)) observed reflections> has a monomeric six-coordinate structure with transoid nitrogen donor atoms, N-Yb-N 143.6(4) deg and an irregular coordination polyhedron described as either a distorted trigonal prism or a monocapped square pyramid.Attempted crystallization of Yb(pin)2(thf) by partial desolvation of Yb(pin)2(thf)4 in hot toluene, containing a trace of dme, gave a mixture of red Yb(pin)2(thf) and orange 2.The latter was independently synthesized by partial desolvation of Yb(pin)2(dme)2 in toluene.An X-ray crystal structure showed 2 1/c, a 11.614(2), b 15.945(7), c 15.327(4) Angstroem β 110.19(2) deg, Z 2 dimers, R 0.070 for 2314 (I>/=3?(I)) observed reflections> to be a dimer with two bridging pin ligands, coordinated through nitrogen only.There is an approximately square pyramidal five-coordinate ytterbium environment with an apical dme oxygen, and with two bridging nitrogens, a terminal nitrogen, and a dme oxygen in the basal plane.
