Dimethyl N,N'-oxalamidodiethanoate.
The title compound, dimethyl 2,2'-(oxalyldiimino)diethanoate, C(8)H(12)N(2)O(6), exhibits a network of hydrogen bonds between amide and ester groups. Molecules lie on inversion centres and show a planar conformation for both the oxalamide and ester groups. The glycine residues adopt a conformation close to the polyglycine II structure.
متن کاملN,N-Dimethyl-N′,N′′-diphenylphosphoric triamide
In the title compound, C(14)H(18)N(3)OP, a crystallographic mirror plane bis-ects the mol-ecule (the C,N,C atoms of the dimethyl-amido moiety and the P=O unit lie on the mirror plane). The P atom has a distorted tetra-hedral geometry; the bond angles at P are in the range 98.98 (11)-115.28 (7)°. In the crystal, the O atom of the P=O group acts as a double hydrogen-bond acceptor for two symmetry...
متن کاملRedetermination of Crystal Structure of N,N'-bis (2-Hydroxybenzylidene)-2,2-Dimethyl-1,3-Propanediamine
The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11)</e...
متن کاملN,N′-Dimethyl-N′′-(trichloroacetyl)phosphoramide
In the title compound, C4H9Cl3N3O2P or CCl3C(O)NHP(O)(NHCH3)2, the P atom has a strongly distorted tetra-hedral geometry due to the formation of intermolecular strong hydrogen bonds involving the N atoms. In the crystal, N-H⋯O=P and N-H⋯O=C hydrogen bonds connect the mol-ecules into a two-dimensional array parallel to (100). An intra-molecular P⋯O contact [P⋯O = 2.975 (3) Å] is observed. The CC...
متن کاملSynthesis and X-ray Crystal Structure of N’-Cyano-N,N’-dimethyl-4-nitrobenzohydrazide
Using a two-step procedure, N’-cyano-N,N’-dimethyl-4-nitrobenzohydrazide was synthesized. The structure was established using single crystal X-ray diffraction. It crystalized in the orthorhombic space group P212121 where a = 8.1974(6), b = 10.6696(7), and c = 12.9766(8) Å. The first reported crystal structure of an acyclic cyanohydrazide is discussed with a focus on the geometry of the hydrazid...
