该资源是一篇学术论文，讨论了Adipato-Bridged Mixed Ligand catena Complexes（脂肪酸桥联混合配体链状复合物）的合成与结构，涉及金属离子NiII, CuII, ZnII与配体Adipic Acid（己二酸）的配合物。
在论文中，作者报告了三种由Adipic Acid桥联的混合配体catena复合物，其化学式为`[M(phen)(H2O)]L2/2`，其中M代表金属离子NiII、CuII或ZnII，phen是邻菲啰啉（1,10-菲啰啉）配体，H2O表示水分子，而L2/2则代表两个Adipic Acid配体。这些复合物通过X射线衍射分析确定了它们的晶体结构，发现它们在同一空间群C2/c（编号15）中等构晶，具有类似的单元参数。
对于这三种复合物，它们的晶胞参数如下：
- 对于NiII复合物（1），a = 22.451(4) Å, b = 9.041(1) Å, c = 17.440(2) Å, β = 103.41(1)°, U = 3443.4(9) ų, Z = 8；
- 对于CuII复合物（2），a = 22.479(2) Å, b = 9.067(1) Å, c = 17.494(3) Å, β = 103.67(1)°, U = 3464.6(8) ų, Z = 8；
- 对于ZnII复合物（3），a = 22.635(3) Å, b = 9.052(1) Å, c = 17.571(3) Å, β = 103.24(1)°, U = 未给出, Z = 8。
这些结构的共同特点是，金属离子M被一个邻菲啰啉和一个水分子配位，同时与两个己二酸分子形成桥联，构建出链状结构。己二酸的双羧基与金属离子形成配位键，增强了化合物的稳定性和结构多样性。
这项研究揭示了配体Adipic Acid在金属配合物中的作用，以及它如何影响配合物的几何构型和晶体结构。这些化合物可能具有潜在的应用价值，例如在催化、磁性材料、光谱学和药物传递系统等领域。由于它们的结构特性，这些复合物可能表现出不同的化学和物理性质，为进一步探索配位化学和功能材料设计提供了有价值的信息。

Introduction
In recent years, extensive efforts have been dedicated to the
design and construction of coordination polymers because
their supramolecular architectures with specific topologies
may endow them with promising properties for technologi-
cal and industrial applications [1]. Rigid bridging ligands
have been widely used for the self-assembly of metal atoms
into diverse supramolecular systems [227]. Our research in-
terests have been intensively focused on exploring the satu-
rated α,ω-dicarboxylate anions as bridging ligands to con-
struct coordination polymers since their carboxylate O

atoms are all capable of participating in coordination to
metal atoms along with the flexibility resulting from the C-
C single bond skeleton.
Recent investigations on a series of transition metal di-
carboxylates showed that the α,ω-dicarboxylate anions
tend to function as bis-monodentate or bis-bidentate li-
gands to bridge metal atoms into 1D chains, 2D layers
and 3D networks [8217]. Further studies on Cu(II) mixed
ligand dicarboxylato complexes [18] indicate that the mo-
lecular recognition of the incorporated phen ligands based
on π-π stacking interactions promotes supramolecular as-
semblies of the α,ω-dicarboxylato bridged coordination
polymers.
To our knowledge, however, a bis-chelating bridging fash-
ion of the α,ω-dicarboxylato ligands in coordination poly-
mers has not been reported yet. As an ongoing part of our
research, we report here on the syntheses and crystal struc-
tures of three adipato bridged transition metal coordination
polymers, in which the adipate anions act as bis-chelating
bridging ligands.
