Synthesis and crystal structure of pyridine and methanol coordinated α-octabutyloxyphthalocyaninatocobalt (II)

Crystal structure of pyridine and methanol axially coordinated 1,4,8,11,15,18,22,25- octabutyloxyphthalocyaninatocobalt(II)(viz.α-octabutyloxyphthalocyaninatocobalt) {[(n-BuO)8Pc]@Co(Py)(MeOH)} (1) was determined by X-ray diffraction methods. Crystal data: monoclinic, space group P21/n, Z = 4, a = 1.06482(4), b = 3.5487(2), c = 1.79428(9)nm, β=103.246(2)°, V = 6.5792(5) nm3, μ = 0.325 mm-1. The result shows that the ring skeleton of 1 maintains planar conformation, which is similar to that of unsubstituted phthalocyanine but is remarkably different from the saddle shapeconformation of 1,4,8,11,15,18,22,25-octabutyloxyphthalocyaninatocopper (II) {[(n-BuO)8Pc]Cu}(2), which has no axial coordination. In the structure of 1, the substituents butyloxy groups of 1 somewhat deviate from the ring plane, while pyridine and methanol are coordinated to the center atom Co from opposite sides of the ring plane. In addition, all molecules are stacked along axis a to form one-dimensional molecule chain, the neighboring molecules in the chain overlap to some extent with a benzene ring and a distance of 0.3565 nm.     

Synthesis and crystal structure of pyridine and methanol coordinated a-octabutyloxyphthalocyaninatocobalt (II)

Phthalocyanines (Pcs) have been widely used as dyes and pigments, photoelectric materials and catalysts. They also bring general attention for potential applications, for example, in solar batteries and fuel cell, charge battery, electrochromic display devices, liquid crystal, sensors and molecular devices. The Pc抯 properties, such as spectroscopic, electronic, and magnetic properties, thermostabilities, and catalytic activities, may be adjusted by modifying the molecular structure. Therefor…

1,4,8,11,15,18,22,25-八丁氧基酞菁镍(Ⅱ)的合成与性质

酞菁类配合物同天然的卟啉、叶绿素、血红素等有相似的骨架结构,是一类具有π-电子共轭体系的化合物,具有光、电、磁及催化等独特的物理化学性质[1]。由于无取代的酞菁配合物在水和有机试剂中的溶解度低,限制了对其性质和应用的研究,但在酞菁环的周边或轴向位置引入取代基,可大大提高这类配合物在水或有机溶剂中的溶解度。本文参照文献[2],采用ＤＢＵ液相催化法合成了周边烷氧基取代的1,4,8,11,15,18,22,25 八丁氧基酞菁镍(Ⅱ)(结构见下图),并用电子吸收光谱、荧光光谱对其进行表征,测定了其氧化还原性质和溶解性及在氮气气氛中的热稳定…

4-(3-吲哚基)-3-丁烯-2-酮苯甲酰腙Schiff碱过渡金属配合物的合成、表征及生物活性研究

A Schiff base ligand 4-[indol-3-yl]-but-3-en-2-one benzoyl hydrazone (HL), and its four transition metal complexes (ML₂，M=Cu(Ⅱ), Ni(Ⅱ), Zn(Ⅱ) and Co(Ⅱ)) have been prepared and characterized by means of elemental analysis, EI-MS, molar conductivity, IR, UV-Vis and ¹H NMR. The results showed that HL as a bidentate ligand coordinated with transition metal ions to form four-coordination complexes. The antibacterial activity was studied by using the filter scraps diffusion method, and the results indicated that the ligand and the complexes had a low bacteriostatic activity against S. Aureu, P. Aeruginosa and E. Coli. The low in vitro antitumor activity of the title complexes was also observed by using MTT method against KB, A2780, Bel7402 and HELF.
