Luminescent heterohexanuclear complexes with platinum alkynyl and silver diphosphine as components

Reactions between the building blocks [Ag2((mu)-Ph2PXPPh2)2(MeCN)2]^2+ and [Pt(C(identical to)CC6H4R-p)4]^2–(R = H, CH3) afforded strongly luminescent acetylide-linked neutral heterohexanuclear complexes Pt2Ag4((mu)-Ph2PNPPh2)4(C(identical to)CC6H4R-p)4(R = H, 1; CH3, 2) for X= NH, but a heterotrinuclear complex cation [PtAg2((mu)-PPh2CH2PPh2)2(C(identical to)CC6H5)2(CH3CN)2]^2+(3^2+) for X= CH2.
