The Crystal Structure of Tetrakis(N-methylthiourea)copper(I) chloride with an Elaborate Network of Hydrogen Bonding

抄録

The compound tetrakis(N-methylthiourea)copper(I) chloride, [Cu(Metu)₄]Cl (1), was prepared by the reaction of CuCl with N-methylthiourea in a ratio of 1:1 or 1:2. Compound 1 crystallizes in the tetragonal space group I4₁/a. The solid-state structure is composed of tetrahedral [Cu(Metu)₄]⁺ units possessing D₄ symmetry and chloride counter ions, whereby the metal-organic building blocks are joined via N(H)…S hydrogen bridges, leading to a supramolecular 3D-network. Non-coordinated chloride ions also participate in hydrogen bonding.
