Steric Effects of Alkyl Substituents at <em>N</em>-Donor Bidentate Amines Direct the Nuclearity, Bonding and Bridging Modes in Thiocyanato-Copper(II) Complexes
Abstract:A series of Cu(II)-thiocyanato complexes derived from sterically hindered N-donors diamines were synthesized and characterized: catena-[Cu(Me3en)(μ-NCS)(NCS)] (1), catena-[Cu(NEt2Meen)(μ-NCS)(NCS)] (2), catena-[Cu(N,N,2,2-Me4pn)(μ-NCS)(NCS)] (3), the dimeric: [Cu2(N,N′-isp2en)2(μ-NCS)2(NCS)2] (4) and the monomeric complex [Cu(N,N′-t-Bu2en)(NCS)2] (5), where Me3en = N,N,N′-Trimethylethylenediamine, NEt2Meen = N,N-diethyl-N′-methylethylenediamin… Show more
