Synthesis and structural studies of two pyridine-armed reinforced cyclen chelators and their transition metal complexes.
Two novel pyridine pendant-armed macrocycles structurally reinforced by an ethyl bridge, either between adjacent nitrogens (for side-bridged) or non-adjacent nitrogens (for cross-bridged), have been synthesized and complexed with a range of transition metal ions (Co2+, Ni2+, Cu2+ and Zn2+). X-ray crystal structures of selected cross-bridged complexes were obtained which showed the characteristi...
متن کاملSTUDIES OF TRANSITION METAL COMPLEXES WITH 2N-QUINOLYL- AND 2N-ISOQUINOLYL- 1,1,3,3-TETRAMETHY LGUANIDINES
Ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. These compounds have been used as ligands for complexation of transition metals, such as copper(II) and nickel(II). According to the spectrosocopic data, copper(II) cation forms (I: 1) and (I:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (I '-isoquinoly1)- 1,1,3,3-tetr...

Studies on Transition Metal Murexide Complexes
Murexide, a reddish purple compound has the structure shown in Fig. 1. It has received much interest because of its application in chemical analysis and spectrophotometric fields [1, 2]. It is considered as the ammonium salt of purpuric acid and named as ammonium 2,6-dioxo-5-(2,4,6-trioxo-tetrahydro-pyrimidine-5-ylidene amino)-1,2,3,6-tetrahydro-pyrimidine-4-olate. It serves as a metal ion indi...
متن کاملMetal (II) Complexes of Fluconazole: Thermal, XRD and Cytotoxicity Studies
We report thermal, X-ray diffraction (XRD) and cytotoxicity studies of complexes of fluconazole (FCZ) with Cu (II), Fe(II), Cd(II), Co(II), Ni(II), and Mn(II). From XRD measurements, FCZ and its metal complexes were identified as polycrystalline. Marked differences in the X-ray patterns of drug and its metal complexes revealed that the complexes are indeed different compounds and not just the m...
