Poly[bis(μ-purin-9-ido-κ2 N 7:N 9)zinc]
In the title compound, [Zn(C(5)H(3)N(4))(2)], the Zn(II) cation is in a nearly regular tetra-hedral coordination by purinate ligands. Each purinate ligand chelates two Zn(II) cations through two imidazole N atoms of the purinate anion ligand, leading to the formation of a three-dimensional network.

The title complex, [Mg(C7H7N4O2)2(H2O)4], lies across an inversion centre and the Mg(II) atom is coordinated in a slightly distorted octa-hedral environment by four aqua ligands in the equatorial sites and two 1,3-dimethyl-2,6-dioxo-3,7-di-hydro-1H-purin-9-ide ligands, through imidazole ring N atoms, in the axial sites. An intra-molecular O-H⋯O hydrogen bond forms an S(7) graph-set motif. In th...
متن کامل9 - ( 4 - Methoxyquinazolin - 2 - yl ) - 9 H - purin - 6 - amine
A novel hybrid consisting of quinazoline and adenine moieties has been synthesized as a precursor of a potential biologically active target compound. The structure of 9-(4-methoxyquinazolin-2-yl)-9H-purin-6-amine (2) was characterized and confirmed using the following spectroscopic methods: LC-UV-MS, 1H-NMR, 13C-NMR and HSQC-NMR.
متن کاملCrystal structure of tetraaquabis(1,3-dimethyl-2,6-dioxo-7H-purin-7-ido-κN 7)cobalt(II)
The title complex, [Co(C7H7N4O2)2(H2O)4], comprises mononuclear mol-ecules consisting of a CoII ion, two deprotonated theophylline ligands (systematic name: 1,3-dimethyl-7H-purine-2,6-dione) and four coordinating water mol-ecules. The CoII atom lies on an inversion centre and has a slightly distorted octa-hedral coordination environment, with two N atoms of two trans-oriented theophylline ligan...
متن کامل2-Chloro-N-ethyl-9-isopropyl-9H-purin-6-amine
In the title compound, C(10)H(14)ClN(5), the purine ring system is essentially planar, with an r.m.s. deviation from the least-squares plane defined by the nine constituent atoms of 0.0063 (11) Å. In the crystal, mol-ecules are linked by weak N-H⋯N and C-H⋯π inter-actions.
