title: Assembly of a heterometallic polynuclear Sn(IV)-Cu(I) cluster based on Sn(edt)2 (edt = ethane-1,2-dithiolate) as a metalloligand.
abstract: Reaction of [Cu(PPh3)2(MeCN)2]ClO4 (1) and Sn(edt)2 (edt = ethane-1,2-dithiolate) in dichloromethane afforded a novel compound [Sn3Cu4(S2C2H4)6(mu3-O)(PPh3)4](ClO4)2 x 3 CH2Cl2 (2), which is the first example of the heptanuclear Sn(IV)-Cu(I) oxosulfur complex with a bottle-shaped cluster core. Complex 2 gives a blue-green luminescent emission in the solid state. Crystallographic data for 2: C87H90Cl8Cu4O9P4S12Sn3, trigonal, space group R3, M = 2682.02, a = 18.156(2) A, b = 18.156(2) A, c = 54.495(10) A, gamma = 120 degrees, V = 15558(4) A3, Z = 6 (T = 130.15 K).
