From the system metal-cyclam-condensed phosphate is isolated the first complex of {(H₃O⁺)₂[Cu(II)(μ-P₄O₁₂)(cyclam)]}_n(1). This complex was characterized by X-ray diffraction (XRD), spectroscopy (diffuse reflectance, UV–Vis and FT-IR) and thermal analysis (DTA/TGA). The solved molecular structure of 1 revealed one rare 1D-anionic polymeric copper(II)-complex, {[Cu(II)(μ-P₄O₁₂)(cyclam)]^2-}_n, involving two distinct ring ligands (cyclam / cyclotetraphosphate), in which a new coordination mode of the ${\mathrm{P}}_4{\mathrm{O}}_{12}^{4-}$ was observed. The counterions (H₃O⁺) ensure the connection between 1D-polymers by acting as donor in a strong "charge-assisted" hydrogen bonds with P₄O₁₂ rings leading to 2D-supramolecular frameworks arranged in -A-B-A- fashion. The 2D-supramolecular network is stabilized by O/N-H…O interactions whereas the van der Waals contacts play a key role in the consolidation of the 3D packing as verified by Hirshfeld surface analysis in combination with 2D fingerprint plots. The biochemical properties of 1 was also evaluated via DDPH, ABTS, hydroxyl radical scavengers and ferric reducing power (FRP) showing promising antioxidant activities which has been clarified by means of the cyclic voltammetric study.

从系统中金属cyclam缩合磷酸盐中分离所述第一复合物{（H ₃ ö ⁺）₂ [铜（II）（μ-P ₄ ø ₁₂）（cyclam）]} _Ñ （1） 。该复合物的特征在于X射线衍射（XRD），光谱学（漫反射率，UV-Vis和FT-IR）和热分析（DTA / TGA）。该解决分子结构的1揭示一种稀有1D-阴离子聚合铜（II） -络合物，{[铜（II）（μ-P ₄ ø ₁₂）（cyclam）] ^2- } _Ñ，涉及两种不同的环配体（cyclam /环四磷酸），其中一种新的配位方式${\mathrm{P}}_4{\mathrm{Ø}}_{12}^{4-}$被观测到。抗衡离子（H ₃ O ⁺）通过与P ₄ O ₁₂环形成牢固的“电荷辅助”氢键，使供体以-ABA-形式排列的2D超分子骨架，从而确保1D聚合物之间的连接。二维超分子网络通过O / NH…O相互作用而得以稳定，而范德华接触在3D堆积的固结中起着关键作用，这已通过Hirshfeld表面分析与2D指纹图的结合得到了验证。还通过DDPH，ABTS，羟基自由基清除剂和三价铁还原能力（FRP）对1的生化特性进行了评估，这些活性显示出很有希望的抗氧化活性，这已通过循环伏安法研究得以阐明。
