The Co(III) atom in the title compound, [Co(C(12)H(6)N(2)O(4))(C(12)H(7)N(2)O(4))], is six-coordinated in a distorted octa-hedral geometry by four N atoms and two O atoms of the chelating 2,2'-bipyridine-6,6'-dicarboxyl-ate and 6'-carb-oxy-2,2'-bipyridine-6-carboxyl-ate ligands. Intermolecular O-H⋯O hydrogen bonds and face-to-face π-stacking inter-actions [centroid-centroid distance = 3.6352 (1...
The Rh(III) ion in the title compound, [Rh(C(12)H(6)N(2)O(4))(C(12)H(7)N(2)O(4))], is coordinated by four N atoms and two O atoms from two chelating ligands L and HL (H(2)L = 2,2'-bipyridine-6,6'-dicarb-oxy-lic acid) to form a distorted octa-hedral geometry. Face-to-face π-stacking inter-actions are observed between inversion-related pyridine rings, with a centroid-to-centroid distance of 3.581...
In the title compound, [Ni(C(12)H(7)N(2)O(4))(2)]·4H(2)O, the Ni atom is located at the centre of a distorted octa-hedron, formed by four N atoms and two O atoms from the same two tridentating chelated 6-carb-oxy-2,2'-bipyridine-6'-carboxyl-ate (L) ligands. Face-to-face π-stacking inter-actions between inversion-related pyridine rings with centroid-centroid distances of 3.548 (3) and 3.662 (3) ...
The DNA lesion 1,N(6)-ethenoadenine (εA) has been investigated with respect to its metal-binding properties. A synthetic DNA duplex comprising an εA : εA mispair readily forms doubly silver(I)-mediated base pairs εA-Ag(I)2-εA, representing the first example for a dinuclear metal-mediated homo base pair of a purine derivative. It also constitutes the first example for a Hoogsteen-type metal-medi...
In this paper, the parameters of the LTE system in DL are investigated. These parameters include the effect of the Hybrid Adaptive Repeat and Request henceforth (HARQ) on the Signal to Noise Ratio (SNR), Block Error Rate (BLER), and throughput. The paper deals with three cases of Channel Quality Indicator (CQI): 3,7 and 15.The results showed that the HARQ procedure can improve the BLER and the ...
