Synthesis and Crystal Structure of Bis（（2-methoxy-mercaptomethyl-benzene）hexacarbonyldiiron） Complex

摘要

The reaction of [Fe2S2（CO）6] with one equiv.of o-OCH3C6H4CH2Br under the re-duction of LiBHEt3 in dry THF afforded a tetranuclear cluster [（μ4-S）{（μ-SCH2（o-OCH3）Ph）Fe2（CO）6}2]（1）.Complex 1 crystallizes in monoclinic,space group P21 with a = 16.5623（6）,b = 12.8265（5）,c = 18.2702（7） ,β = 115.95（1）o,V = 3489.9（4） 3,Z = 4,μ = 1.87 mm-1,Dc = 1.709 Mg/m3,T = 296（2） K,C28H18Fe4O14S3,Mr = 898.03,F（000） = 1800,S = 1.10,R = 0.032 and wR = 0.058.Complex 1 consists of two diiron fragments possessing a {Fe2（CO）6} core.The two diiron units are bridged by an inorganic sulfide in a μ4-S binding mode and the sulfide is in a distorted tetrahedral geometry with the four iron atoms at each corner of the distorted tetrahedral.In its solid state,two types of non-classic intermolecular hydrogen bonding interactions plus a weak π-π stacking interaction led to a 2-D network.
