Abstract

The first examples of high-dimensional mixed-valence homometallic cyano-bridged copper complexes were synthesized and characterized: net-structured [Cu(CN)4{Cu(cyclam)}1.5] 2n(H2O)5n (1), ladder-type double-chain-structured [Cu(CN)2{Cu(CN)2Cu(cyclam)}] n(H2O)n (2), layer-structured [{Cu(CN) 2}2Cu(cycalm)]n (3), and hydrogen-bond-based 2-D [Cu(CN)3Cu(cyclam)]n(CH3OH)n (4) (cyclam = 1,4,8,11-tetraazacyclotetradecane). 1 crystallizes in triclinic space group P1̄ with a = 8.3589(11) Å, b = 13.478(2) Å, c = 14.828(2) Å, α = 66.895(2)°, β = 77.916(3)°, γ = 85.939(3)°, and Z = 1; 2 crystallizes in triclinic space group P1̄ with a = 8.2305(12) Å, b = 9.8861(15) Å, c = 13.219(2) Å, α = 84.863(3)°, β= 75.744(3)°, γ = 89.818(3)°, and Z = 2; 3 crystallizes in monoclinic space group P21/c with a = 6.830(2) Å, b = 8.482(2) Å, c = 17.306(4) Å, β= 98.144(4)°, and Z = 2; 4 crystallizes in triclinic space group P1̄ with a = 9.470(1) Å, b = 10.034(1) Å, c = 12.064(1) Å, α = 67.325(2), β = 75.593(2), γ = 70.672(2), and Z = 2. The coordination sphere of CuI sites in the complexes shows diverse structures: tetrahedral [CuC4] for 1, tetrahedral [CuC3N] and triangular [CuC2N] for 2, triangular [CuC2N] for 3, and triangular [CuC3] for 4. In particular, 1 constitutes the first example of a structurally characterized system containing a bridging tetrahedral [Cu(CN)4]3- unit. The diverse structural nature of these complexes is governed by the capping amines and the content of water in the reaction media. The magnetic interactions are negligible in these mixed-valence complexes.
