[Cu3(dppm)3(μ 3-I)2][(0.5TCNQ)], a radical salt derived from a donor with a copper(I) trimer

A radical salt 1, [Cu 3 (dppm) 3 (μ 3 -I) 2 ][(0.5TCNQ)], has been prepared by reaction of CuI, dppm (diphenylphosphinomethane) and TCNQ (7,7′,8,8′-tetracyanoquinodimethane) with a molar ratio of 1 : 1 : 0.5 and characterized by IR, UV-Vis and solid-emission spectroscopy. Its structure was determine...

Summary:A radical salt 1, [Cu 3 (dppm) 3 (μ 3 -I) 2 ][(0.5TCNQ)], has been prepared by reaction of CuI, dppm (diphenylphosphinomethane) and TCNQ (7,7′,8,8′-tetracyanoquinodimethane) with a molar ratio of 1 : 1 : 0.5 and characterized by IR, UV-Vis and solid-emission spectroscopy. Its structure was determined by X-ray crystallography. 1 also has photoluminescence (λ max = 653 nm) at room temperature. Magnetic properties indicate that TCNQ is in the reduced state (TCNQ 2− ).
