Abstract

A racemic heterometallic dinuclear compound, rac-[Sn(C2H4O2S)3Zn(C12H8N2)2], conventionally abbreviated rac-[SnL3Zn(Phen)2] (1), where L is mercaptoacetato and Phen is 1,10-phenanthroline, is described. It contains one main group metal centre of Sn(IV) and one transition metal centre of Zn(II), and by design, links the Zn(II) centre to the building unit of the sulfur-contained (Δ/Λ) SnL32- complex anion. In this cluster, the Sn(IV) center is coordinated by three O atoms and three S atoms from three meraptoacetato ligands to form a [SnO3S3] octahedral coordination sphere. The Zn(II) centre is found in a very distorted [ZnON4] triangle bipyramid coordination sphere, four N atoms from two chelated Phen liagnds and one O atom

ACCEPTED MANUSCRIPT 2 from the µ2-mercaptoacetato ligand of the (Δ/ L ) SnL32 unit. By virtue of three sets of strong π···π stacking interactions, all of clusters fuse together to give out a wavelike supramolecular layer structure along the bc plane. These layers are further connected by two sets of weak hydrogen bonding interactions, thus form a three-dimensional supramolecular framework structure. The photoluminescence property of complex (1) has also been studied on the as-synthesized powder sample.

ACCEPTED MANUSCRIPT 3 1. Introduction

Oxo/sulfur-bridged heterometallic coordination clusters/polymers have attracted considerable interest due to their rich structural variety and potential application for semiconductors, nonlinear optical, luminescent materials, or magnetic materials.1 There are two routes that could be employed to achieve these heterometallic structures: (i) self-assembled technique by utilizing the spontaneous reaction of some organic ligands and two or more different metallic ions and (ii) rational stepwise assemble. In the later approach, e.g., one metallic ion reacts with one
