Structure and magnetism of novel mixed-anionic-group compounds M2(SeO3)(Te3O7) (M = Co2+, Ni2+)
Abstract Novel mixed-anionic-group compounds M 2 (SeO 3 )(Te 3 O 7 ) (M = Co2+ , Ni 2+ ) are successfully synthesized by a conventional hydrothermal method. Two compounds are isostructural which crystallize in the orthorhombic system of a space group Pnma . The framework shows a (MO 6 ) ∞ chain structure along the b -axis, while SeO 3 groups are isolated and Te 3 O 7 groups form the (Te 3 O 7 ) ∞
摘要 采用常规水热法成功合成了新型混合阴离子基团化合物M 2 (SeO 3 )(Te 3 O 7 ) (M = Co 2+ , Ni 2+ )。两种化合物是同构的,它们在空间群 Pnma 的斜方晶系中结晶。该框架显示沿 b 轴的 (MO 6 ) ∞ 链结构,而 SeO 3 基团是孤立的,Te 3 O 7 基团形成沿 a 轴延伸的 (Te 3 O 7 ) ∞ 链。这是首次实现与Se 4+ 和Te 4+ 阴离子基团共存的过渡金属化合物。磁性测量表明,Co 2 (SeO 3 )(Te 3 O 7 ) 在~11 K 具有反铁磁有序性,而 Ni 2 (SeO 3 )(Te 3 O 7 ) 在~31 K 具有类似的反铁磁有序性。此外,使用自旋链模型拟合磁化率得出交换耦合 J /k B = -1。

A method of making benzidine hydrogen selenite complex with Cobalt and Platinum as surfactants is discussed. The resultant benzidine hydrogen selenite complex with either Cobalt or Platinum was characterized for its unique and superior properties. The complexes were characterized by elemental analysis, FTIR, and spectroscopy. The critical micelle concentration and thermodynamic parameters were calculated. The Values of IC50 were also calculated for the prepared complexes as well as their parent complex. The method of using the benzidine hydrogen selenite complex with cobalt and platinum as an antitumor agent to treat cancer is also demonstrated.

which can be prepared in a one‐step reaction and in an extraordinary high yield of 95 %, has been evaluated as ligand in energetic coordination compounds. For the first time 25 new transitionmetal complexes (Mn2+, Ni2+, Co2+, Cu2+, and Zn2+) using methylsemicarbazide (1) as the ligand were prepared and comprehensively analyzed by, for example, XRD, IR, EA, UV/Vis and DSC/DTA/TGA. Many show a strong
