LIGAND TRANSFER FROM A TRIS(IMINO)STANNATE ANION - SYNTHESES AND STRUCTURES OF [(CU[MU-N=C(BU(T))PH])(4)]CENTER-DOT-THF (THF=TETRAHYDROFURAN) AND CU[MU-N=C(BU(T))PH])(4)(PPH(3))(2)]CENTER-DOT-6THF

The Group 11 metal imino complexes [{Cu[mu-N = C(BUt)Ph]}(4)]. thf 2 ( thf = tetrahydrofuran) and [{CU[mu-N=C(BUt)Ph]}(4)(PPh(3))(2)]. 6thf 3 have been prepared by the unusual ligand-transfer reactions of the tr is(imino)stannate complex Sn[mu-N = C(BUt)Ph]Li-3 . thf with CuCl; bot h complexes have been shown by crystallography to contain planar Cu-4 cores.
