Diethyl 2-(triphenylmethyl)malonate
In the title compound, C(26)H(26)O(4), steric crowding of the Ph(3)C- group with the -CH(CO(2)Et)(2) unit leads to a long C-C bond [1.585 (2) Å]. One of the two ethyl groups is disordered over two sites in a 60:40 ratio.
متن کاملDiethyl 2-(2-nitrobenzylidene)malonate
In the title compound, C(14)H(15)NO(6), the ethoxy-carbonyl groups adopt extended conformations. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of C-H⋯O hydrogen bonds with a R(2) (2)(20) motif.

In the title compound, C(14)H(16)BrNO(4), inter-molecular C-H⋯O hydrogen bonds link the mol-ecules, forming a stable structure. An intra-molecular N-H⋯O hydrogen bond results in the formation of a six-membered ring and helps to establish the mol-ecular conformation which is almost planar, with an r.m.s deviation of 0.0842 Å.

In the title mol-ecule, C(14)H(8)N(2)O(5), the amino group is involved in the formation an intra-molecular N-H⋯O hydrogen bond. In the crystal, weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules into ribbons along the b axis.

The title mol-ecule, C(37)H(56)O(6), possesses twofold symmetry, with the twofold axis passing through the quaternary C atom. In the crystal, neighbouring mol-ecules are linked via O-H⋯O hydrogen bonds involving the phenol OH group and the carbonyl O atom, forming chains propagating in [101]. Within these chains, rings are formed with an R(2) (2)(20) motif. There are also C-H⋯O inter-actions pr...
