N 6,3′-cyclo-5′-O-Cyanomethylthymidine
The title compound, C(19)H(20)N(4)O(4), is a cyclo-nucleoside with a C-N linkage. The furan-ose ring adopts a twist C3'-endo/C2'-exo (close to (3)T(2)) conformation with a pseudorotational phase angle (P) of 8.1° and puckering amplitude (v(m)) of 30.6°. The orientation of the pyrimidine ring with respect to the sugar group is anti. One intra-molecular C-H⋯O hydrogen bond is observed. The packin...

Recently, new spreading sequences have been proposed to multiplex the capacity of users. In particular, Weyl spreading sequences have the larger capacity of users than the Gold code. This paper shows that Weyl spreading sequences appear in bit recovering model and they are orthogonal basis. This result shows the reason why they have the large capacity and that any spreading sequence is expresse...
متن کاملcyclo-Tetrakis(μ-3-acetyl-4-methyl-1H-pyrazole-5-carboxylato-κ4 N 2,O 3:N 1,O 5)tetrakis[aquacopper(II)] tetradecahydrate
The title compound, [Cu(4)(C(7)H(6)N(2)O(3))(4)(H(2)O)(4)]·14H(2)O, a tetra-nuclear [2 × 2] grid-type complex with S4 symmetry, contains four Cu(II) atoms which are bridged by four pyrazole-carboxyl-ate ligand anions and are additionally bonded to a water molecule. Each Cu(II) atom is coordinated by two O atoms of the carboxyl-ate and acetyl groups, two pyrazole N atoms of doubly deprotonated 3...
متن کاملcyclo-Tetra-μ-malato-κ16 O,O′,O′′:O′′′-tetrakis[bis(1H-benzimidazole-κN 3)cobalt(II)] eicosahydrate
The title compound, [Co(4)(C(4)H(4)O(5))(4)(C(7)H(6)N(2))(8)]·20H(2)O, consists of tetra-nuclear Co(II) complexes and disordered uncoordinated water mol-ecules. The tetra-meric complex mol-ecule has symmetry. While two benzimidazole mol-ecules and a tridentate malate dianion coordinate a Co(II) ion, the carboxylate O atom from an adjacent malate dianion bridges the Co(II) ions to complete a dis...

The asymmetric unit of the title tetra-nuclear niobium(V) compound, [Nb(4)(C(2)H(5)O)(8)(C(5)H(7)O(2))(4)O(4)], contains two Nb(V) atoms, two bridging O atoms, two acetyl-acetonate and four ethano-late ligands. Each Nb(V) atom is six-coordinated by the bridging O atoms, two ethano-late and one chelating acetyl-acetonate ligands. The Nb-O distances vary between 1.817 (2) and 2.201 (2) Å and the ...
