Sn(IV) and organotin(IV) compounds of the type SnL2X2(X = Cl and HL = 5-acetyl-, benzol-, or phenylazo-, 8-quinolinol), SnX4 · 2HL′(X = Cl or Br and HL′=8-quinolinol-N-Oxide), R2SnL2(R = CH3, C2H5, C4H9, C8H17 or C6H5) and R3SnL(R = C6H5) have been synthesized and characterized. The 119mSn Mössbauerspectra of these compounds have been recorded at 77°K and probable structures from the Mössbauer parameters
SnL 2 X 2类型的几种Sn(IV)和有机锡(IV)化合物(X = Cl,HL = 5-乙酰基,苯甲酰基或苯偶氮基,8-喹啉醇),SnX 4 ·2HL'(X = Cl或Br且HL'= 8-喹啉醇-N-氧化物),R 2 SnL 2(R = CH 3,C 2 H 5,C 4 H 9,C 8 H 17或C 6 H 5)和R 3 SnL (R = C 6 H 5)已经合成并表征。在119米这些化合物的SnMössbauer光谱已在77°K记录下来,并根据Mössbauer参数推断出可能的结构。R 2 SnL 2螯合物(QS =约2.0 mm / sec。)被认为具有两个R-基团在八面体结构中占据顺式位置。化合物SnX 4 ·2HL'的Mössbauer光谱已通过图形解析,四极分裂值(约0.75 mm / sec。)强烈暗示了Sn(IV)四卤化物加合物的反式构型。
Thermal properties, geometrical structures, antimicrobial activity and DNA binding of supramolecular azo dye complexes
using Coats–Redfern and Horowitz–Metzger methods. The ligands (HLn) and Ru(III) complexes are screened for their antimicrobial activity against bacterial and fungal species. The tested complexes (1) and (2) have good antibacterialactivity against Bacillus cereus and the tested ligands (HL2, HL3 and HL5) have good antifungal activity against Aspergillus niger and also HL5 showed against Alternaria alternata
制备5-(4-衍生物苯基偶氮)-8-羟基喹啉(HL n)的Ru(III)配合物,并通过元素分析,IR,UV-可见光谱,1 H和13 C NMR光谱,质谱,X表征射线衍射分析,电导率测量和磁化率测量以及热分析。X射线衍射图谱表明配体(HL 3)具有多晶性质和络合物(2)是完全无定形的。所述配体通过取代来自CN和OH基团的质子而充当通过CN和OH基团配位的二元双齿。摩尔电导率表明Ru(III)络合物本质上是非电解质。光谱表明,所有络合物都是八面体,其中两个氯化物附着在金属离子上。研究了配位体(HL n)和Ru(III)配合物的最佳键长,键角和计算的量子化学参数。分子对接用于预测偶氮染料配体与前列腺癌突变体2q7k激素受体之间的结合。活化热力学参数,例如活化能(E a),焓(ΔH⁎),熵(ΔS⁎))和吉布斯分解的自由能变化(ΔG⁎)是使用Coats–Redfern和Horowitz–Metzger方法计算的。筛选配体(HL

potential drug molecules. Here, we report the synthesis and characterization of four new ruthenium (II) azo-8-hydroxyquinoline complexes, their mode of in vitro DNA binding and antiproliferative properties against cultured human cancer cell lines. The activity of these compounds prior to photoirradiation is minimal. However, they could induce DNA photonuclease activity through the generation of reactive oxygen

5‐phenylazo‐8‐hydroxyquinoline and its newly metal complexes with Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) metal ions have been prepared and characterized using different analytical techniques. The complexes are distorted octahedral binding via one oxygen and nitrogen atoms of the ligand; two/three coordinated water molecules. 1:1 complexes contain one chloride or OH− ion and some complexes have one
