The coordinated phen molecules of the adjacent Mn(phen)2(N3)2 moieties experience π-π stacking which is responsible for the crystal packing. In complex 2, the Mn atom is coordinated by five nitrogen atoms of two phen molecules and one N3- ion with the Mn-N distances ranging from 2.152(5) to 2.291(5)?. The approximately octahedral environment was completed by the oxygen atom of the coordinated water molecule with the Mn-O distance of 2.180(5)?. The hydrate water molecule is hydrogen-bonded to one of the O atoms of free ClO4- anion. ?  相似文献

Each L ligand links two Cu(Ⅱ) atoms using its imidazole groups to form an infinite one-dimensional (1D) ladder-like chain, which further linked by SO42- to form a two-dimensional (2D) network structure. The 2D sheets are further connected by C-H…O hydrogen bonds to give a three-dimensional (3D) structure. CCDC: 650388.  相似文献
