چکیده
The mol-ecule of the title compound, C(6)H(7)N(3)O(2), a derivative of o-phenyl-enediamine, nearly shows non-crystallographic C(s) symmetry. C-C-C angles span the range 116.25 (11)-122.35 (11)°. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen bonds connect mol-ecules into undulating sheets perpendicular to the crystallographic a axis. A weak intra-molecular N-H⋯O hydrogen bond is also observed. No π-stacking is observed in the crystal structure.

In the title layered coordination polymer, [Na(4)(C(8)H(3)NO(6))(2)(H(2)O)(3)](n), the doubly deprotonated 3-nitro-benzene-1,2-dicarboxyl-ate ligands exhibit μ(8)- and μ(6)-coordination modes to the sodium ions, generating sheets lying parallel to (001). The coordination environments of the sodium ions are distorted octa-hedral, distorted trigonal-bipyramidal and moncapped trigonal-prismatic. O...

In order to develop platinum complexes with selective activity in primary and secondary bone malignancies and with the aim to optimize antitumor activity, platinum(II) complexes with aminotris(methylenephosphonic acid) as bone-seeking (osteotropic) ligand have been synthesized, characterized and tested in the cisplatin-sensitive ovarian carcinoma cell line CH1. As non-leaving diamine ligands, w...
متن کاملChemo- and enantioselective Rh-catalysed hydrogenation of 3-methylene-1,2-diazetidines: application to vicinal diamine synthesis.
Rhodium catalysed hydrogenation of 3-methylene-1,2-diazetidines with a range of chiral ligands is reported. Using Mandyphos, excellent levels of chemo- and enantioselectivity (up to 89% ee) can be achieved. Reductive cleavage of the derived 3-substituted 1,2-diazetidine with LiDBB provides the enantioenriched biscarbamate protected 1,2-diamine.
متن کامل[N,N-Bis(2-aminoethyl)ethane-1,2-diamine](ethane-1,2-diamine)nickel(II) thiosulfate trihydrate
The title compound, [Ni(C(2)H(8)N(2))(C(6)H(18)N(4))]S(2)O(3)·3H(2)O, was accidentally synthesized under solvothermal conditions applying [Ni(en)(3)]Cl(2) (en is ethane-1,2-diamine) as the Ni source. The asymmetric unit consists of one discrete [Ni(tren)(en)](2+) complex [tren is N,N-bis-(2-amino-eth-yl)ethane-1,2-diamine] in which the Ni(2+) cation is sixfold coord-inated within a slightly dis...
