چکیده
In the title mol-ecule, C(11)H(16)NO(6)P, the nitro group is twisted out of the mean plane of the benzene ring at 29.91 (3)°. The two ethyl groups are disordered between two orientations in the ratios 0.784 (7)/0.216 (7) and 0.733 (6)/0.267 (6). Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.

In the title compound, C(9)H(12)NO(6)P, intra-molecular C-H⋯O hydrogen bonds form five- and six-membered rings. In the crystal, inversion dimers lined by pairs of C-H⋯O hydrogen bonds occur with ring motifs R(2) (2)(10). The O atom of the hydr-oxy group behaves as an accepter and the benzene ring as donor. Adjacent dimers are connected through O-H⋯O links.

Mol-ecules of the title compound, C(11)H(17)O(4)P, are linked into chiral helical chains along the crystallographic b axis via O-H⋯O hydrogen bonds between the hydr-oxy group and an O atom of the phospho-nate group. One ethyl group is disordered over two positions; the site occupancy factors are ca 0.7 and 0.3.

The title compound, C(20)H(23)N(4)O(6)PS, was synthesized by the reaction of N-(4-methoxy-benzyl-idene)-5-(4-nitro-phen-yl)-1,3,4-thia-diazol-2-amine and diethyl phosphite. The thia-diazole and nitro-substituted phenyl rings in the mol-ecule are approximately coplanar, the dihedral angle being 5.3 (2)°. The dihedral angle formed by the mean plane through all non-H atoms of both the thia-diazole...

In the title compound, C(24)H(25)O(7)P, the δ-valerolactonyl ring exists in a distorted screw-boat conformation with the diethoxy-phosphoryl substituent occupying an axial position. The latter adopts an almost syn-periplanar conformation around the P-C bond. The mol-ecules form centrosymmetric dimers connected by O-H⋯O hydrogen bonds.
