A metallopolymer, [Cu(abt)]∞ (abt, 2-aminobenzenethiol) with novel structural patterns resembling black phosphorus

A copper(I) complex of 2-aminobenzenethiol, [Cu(abt)]∞ (1), has been synthesized and characterized. The crystal structure determination indicates a two-dimensional metallopolymeric network formed by edge and corner sharing [Cu(μ3-S)N] coordination tetrahedra wherein the copper(I) centers are coordinated to three bridging thiolate donors and the amino group of 2-aminobenzenethiolate. The copper, the sulfur and the nitrogen atoms form sub-lattices that reveal independently striking similarities to the double-layers present in black phosphorus.

Graphical abstractThe polymeric complex, [Cu(abt)]∞ shows unique tetrahedral connectivity and – reduced to the copper–sulfur arrangement – close structural resemblance to the double-layer lattice of black phosphorus.Figure optionsDownload full-size imageDownload as PowerPoint slide
