摘　　要：Reaction of (NH 4) 2MoS 4 with [Cu(MeCN) 4](BF 4) and (n-Bu) 4NBr in CH 2Cl 2 afforded a new hexanuclear cluster [(n-Bu) 4N] 3[MoS 4Cu 5Br 6] (1). 1 crystallizes in the monoclinic system, space group P2 1/c, with lattice parameters a=1.17383(4) nm, b=2.40136(4) nm, c=2.64112(5) nm, β=94.2020(5)°, V=7.4247(5) nm 3 and Z=4. The structure of the [MoS 4Cu 5Br 6] 3- trianion of 1 is composed of one nido-like [MoS 3Cu 3] core and one half-open cubane-like [MoS 3Cu 3Br] core, which are interconnected by sharing the same MoSCuS plane. The Mo...Cu distances vary in the range of 0.2622(6)-0.2692(5) nm.Reaction of (NH 4) 2MoS 4 with [Cu(MeCN) 4](BF 4) and (n-Bu) 4NBr in CH 2Cl 2 afforded a new hexanuclear cluster [(n-Bu) 4N] 3[MoS 4Cu 5Br 6] (1). 1 crystallizes in the monoclinic system, space group P2 1/c, with lattice parameters a=1.17383(4) nm, b=2.40136(4) nm, c=2.64112(5) nm, β=94.2020(5)°, V=7.4247(5) nm 3 and Z=4.
