N2 - A new organic metal based on the π-donor bis(ethylenedioxy)tetrathiafulvalene, (BEDO-TTF)4[C4N6]·H2O, has been isolated as the N,N′,N″-tricyanoguanidinate monohydrate salt. The crystal structure indicates strong two-dimensional (2D) behavior in the BEDO-TTF donor layer demonstrated by the close intermolecular C-H⋯O, S⋯S, and S⋯O contacts. The N,N′,N″-tricyanoguanidinate dianions are puckered and form dimers through hydrogen bonding with two water molecules, resulting in an infinite sheet of dianions that complement the 2D nature of the BEDO-TTF donor layers. Four-probe resistance, tunnel diode oscillator, and EPR measurements indicate metallic behavior down to 8 K where a metal-semiconductor transition occurs. (BEDO-TTF)4[C4N6]·H2O crystallizes in the P1 space group with a = 11.9628(2), b = 14.1016(2), c = 17.0830(2) Å, α = 81.27(1), β = 70.21(1), γ =77.04(1)°, V =2633.39(7) Å3, Z = 2.
