[Cu(1,4-C4H12N2)2(ClO4)2]n(H2O)2n, a novel butane-1,4-diamine-bridged two-dimensional copper(II) square network: Synthesis, structure, and magnetic properties

A novel butane-1,4-diamine-bridged copper(II) compound was synthesized via solvent diffusion route with high yield. Each copper is coordinated by four butane-1,4-diamine ligands, each of which in turn links with two copper atoms to form a two-dimensional (2D) square network. Interestingly, the title compound features a cross-linking rhombic channel (ca. 5.06 × 14.73 Å) parallel to the crystallographic b axis. And magnetic result measured indicates the presence of localized unpaired electrons in the structure and thus the cupric Cu(II) state.
