Unusual metal-organic frameworks built from 2D layers through Cl⋯Cl contacts and hydrogen bonds

Unusual metal-organic frameworks [M(dtcp)2](SCN)2 [M = Zn, Mn; dtcp = 2,6-di(1,2,4-triazol-1-ylmethyl)-4-chlorophenol] are composed of 2D rhombus-type grid networks associated mutually by remarkable Cl⋯Cl contacts and hydrogen bonds (C–H⋯N and C–H⋯S). Both thermogravimetric analysis and photoluminescence measurements are performed as well to characterize these supramolecular frameworks.
