The new copper(I) sheet compound [Cu 2Cl 2(pyz)] n (pyz = pyrazine) ( 1) has been synthesized and characterized. 1 crystallizes in the triclinic, space group P 1 with a = 6.885(2) A ̊ , b = 7.5719(6) A ̊ , c = 3.752(1) A ̊ , α = 98.84(1)°, β = 92.27(2)°, γ = 106.55(2)°, U = 184.55(7) A ̊ 3, and Z = 1 . Crystal structure consists of one-dimensional CuCl n ladders and stacked pyz columns. Infinite, zigzag ribbons are formed by Cu(I) ions and chlorides. The ladders extend along the c-direction, and are linked by pyz molecules which coordinate to adjacent copper atoms, forming a two-dimensional sheet. The pyz molecules are stacked in the sheet and make a column along the c-axis.
