Crystal structure of 1′-(2-methylpropyl)-2,3-dihydrospiro[1-benzothiopyran-4,4′-imidazolidine]-2′,5′-dione
In the title compound, C15H18N2O2S, the 2,3-di-hydro-1-benzo-thio-pyran ring adopts a sofa conformation and the hydantoin ring is twisted with respect to the benzene ring at 78.73 (17)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers.
متن کاملCrystal structure of 1′-ethylspiro[chroman-4,4′-imidazolidine]-2′,5′-dione: a hydantoine derivative
The title compound, C13H13N2O3, a hydantoin derivative, crystallized with two mol-ecules (A and B) in an asymmetric unit. In mol-ecule A, the imidazolidine ring is twisted about the C-N bond involving the spiro C atom, while in mol-ecule B this ring is flat (r.m.s. deviation = 0.010 Å). The pyran rings in both mol-ecules have distorted half-chair conformations. The mean plane of the imidazolidi...

In the asymmetric unit of the title organic-inorganic hybrid material, 2{H(3)[PW(12)O(40)]}·4C(3)H(4)N(2)O(2)·C(7)H(8)N(4)O(4)·21.5H(2)O, there are four crystallographically independent hydantoin mol-ecules, one dimerized hydantoin mol-ecule, viz. 1,1'-methyl-enebis(imidazolidine-2,4-dione, two independent H(3)PW(12)O(40) mol-ecules and 21.5 solvent water mol-ecules. Nine of the solvent water m...
متن کامل(E)-1-[(2-Hydroxy-1-naphthyl)methylideneamino]imidazolidine-2,4-dione
The title compound, C(14)H(11)N(3)O(3), adopts an E or trans configuration with respect to the C=N bond. In the mol-ecule there is an intra-molecular O-H⋯N hydrogen bond involving the hy-droxy substituent at the 2-positon of the naphthalene ring and the adjacent methyl-ene-amino N atom. The mol-ecule is roughly planar, the dihedral angle between the naphthalene and imidazolidine-2,4-dione mean ...
متن کامل1-(4-Methoxyphenyl)imidazolidine-2,4-dione
In the title compound, C(10)H(10)N(2)O(3), the dihedral angle between the benzene and imidazolidine rings is 6.0 (4)°, consistent with an essentially planar mol-ecule. In the crystal, inter-molecular N-H⋯O hydrogen bonding between centrosymmetrically related mol-ecules leads to loosely associated dimeric aggregates. These are connected into a three-dimensional network by C-H⋯O inter-actions, as...
