Hydrothermal reactions of manganese(II) salts with m-sulfophenylphosphonic acid (m-HO3S-Ph-PO3H2, H3L) and 1,10-phenanthroline (phen) led to six novel manganese(II) sulfonate-phosphonates, namely, [Mn2(HL)2(phen)4]Mn2(HL)2(phen)4(H2O).6H2O (1), [Mn4(L)2(phen)8(H2O)2]ClO4.3H2O (2), [Mn(phen)(H2O)4]2[Mn4(L)4(phen)4].10H2O (3), [Mn6(L)4(phen)8(H2O)2].4H2O (4), [Mn6(L)4(phen)8(H2O)2].24H2O (5), and [Mn6(L)4(phen)6(H2O)4].5H2O (6). The structure of 1 contains two types of dinuclear manganese(II) clusters, and 2-3 exhibit two types of tetranuclear manganese(II) cluster units. 4-5 feature two different types of isolated hexanuclear manganese(II) clusters, whereas the hexanuclear manganese(II) clusters in 6 are bridged by sulfonate-phosphonate ligands into a 1D chain. Magnetic property measurements indicate that there exist weak antiferromagnetic interactions between magnetic centers in all six compounds.
锰(II)盐与间磺基苯膦酸(m-HO₃S-Ph-PO₃H₂,H₃L)和1,10-菲咯啉(phen)的水热反应生成了六种新型的磺酸根-膦酸根锰(II)配合物,即[Mn₂(HL)₂(phen)₄]Mn₂(HL)₂(phen)₄(H₂O).6H₂O(1)、[Mn₄(L)₂(phen)₈(H₂O)₂]ClO₄.3H₂O(2)、[Mn(phen)(H₂O)₄]₂[Mn₄(L)₄(phen)₄].10H₂O(3)、[Mn₆(L)₄(phen)₈(H₂O)₂].4H₂O(4)、[Mn₆(L)₄(phen)₈(H₂O)₂].24H₂O(5)和[Mn₆(L)₄(phen)₆(H₂O)₄].5H₂O(6)。1的结构包含两种双核锰(II)簇,2 - 3呈现两种四核锰(II)簇单元。4 - 5具有两种不同类型的孤立六核锰(II)簇,而6中的六核锰(II)簇通过磺酸根-膦酸根配体桥连形成一维链。磁性测量表明,所有六种化合物的磁性中心之间均存在弱反铁磁相互作用。
