In this work, we focus on multiple interactions of hydrogen bondings of adenines as control factors of molecular arrangements. Two one-dimensional manganese complexes, [Mn_2(naphtmen)_2(L)](ClO_4)・2Et_2O・2MeOH・H_2O and [Mn_2(naphtmen)_2(HL)](ClO_4)_2・MeOH were synthesized by using a bridging ligand including a nucleobase moiety, 6-amino-9-β-carboxyethpurine (HL), and salen-type manganese dinuclear complex, [Mn_2(naphtmen)_2(H_2O)_2](ClO_4)_2 (naphtmen^2_=N,N'-(1,1,2,2-tetramethylethylene) bis(naphthylidene-iminato)dianion). Manganese salen-type units, which are out-of-plane dimer bridged by phenoxo groups, are linked by HL ligands thorough carboxylate bridges in syn-anti mode to form one-dimensional chain structure, where each chain is magnetically isolated by hydrogen bondings of nucleobase units. Cryomagnetic studies reveal that both complexes show SCM properties.

在这项工作中，我们专注于腺苷的氢键的多种相互作用，作为分子排列的控制因素。两种一维锰络合物，[Mn_2（Naphtmen）_2（L）]（Clo_4）・2ET_2O ・2MeOH 2MeOH H_2O和[MN_2（NAPHTMEN）_2（NAPHTMEN）_2（HL）]（HL）]（clo_4）（Clo_4）_2 _2・Meoh sybase ssssy a n aud aul a coi a 6-Amino-9-β-羧基二嘌呤（HL）和Salen-Type Manganese Dinuclear综合体，[Mn_2（Naphtmen）_2（H_2O）_2]（clo_4）_2（naphtmen^2_ bis（萘二烯 - 米诺酯）dianion）。锰沙龙型单元是苯氧基组的平面外二聚体桥梁，由HL配体以Syn-Anti模式彻底的羧酸盐桥连接起来形成一维链结构，其中每个链都由核碱基单元的氢键磁性隔离。冷冻磁研究表明，这两种复合物都显示出SCM的性质。
