Abstract
A new zero-dimensional cyanide-based coordination complex consisting of hexacyanocobaltate(III)-based building block and Tm(III) has been synthesized and characterized through single-crystal X-ray analysis, elemental analysis, and TGA analysis. The complex comprises of the cyano-bridged bimetallic assembly, {[Tm(DMF)(2)(CH3OH)(2)(H2O)(2)(mu-CN)Co(CN)(5)]}(2) (1). The neutral complex consists of two Tm-III centers coordinated with DMF, aqua, and methanol groups and bridged via cyanide to two different [Co(CN)(6)](3-) moieties. Each Tm-III has a coordination number of eight and a square antiprismatic geometry. The structure was further proved by thermogravimetric analysis which indicates the formation of complex 1. Brilliant luminescence property of the complex makes it a suitable material for medicinal applications.
