Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2,9-Dimethyl-1,10-phenanthroline hemihydrate, is researched, Molecular C28H26N4O, CAS is 34302-69-7, about Structure of 2,9-dimethyl-1,10-phenanthroline hemihydrate.Computed Properties of C28H26N4O.
The title compound is tetragonal, space group I41/a, with a 14.258(3) and c = 22.286(4) Å; dc = 1.274(1) for Z = 16; final R = 0.041 for 1196 reflections. At. coordinates are given. Pairs of dimethylphenanthroline mols. related by a 2-fold axis are bridged by water mols. lying on the 2-fold axis and H bonded to one of the N atoms in each mol. The H bonds are long and far from linear; O-H 1.06(4), H…N 2.0(4), O…N 3.020(3) Å; O-H…N 154(3)°. This is presumably a consequence of the approx. parallel arrangement of the 2 phenanthroline mols. in the (phen)2.H2O complex, which are tilted 4.7(1)° with respect to each other; the atoms in 1 mol. are 3.50 to 3.81 Å from the plane of the other mol. On the other side of the phenanthroline is another phenanthroline related by a center of symmetry with the atoms of one mol. 3.41 to 3.45 Å from the plane of the other mol. The phenanthroline mol. has close to 2mm symmetry, but the individual C6 rings are tilted ∼1° with respect to each other.
After consulting a lot of data, we found that this compound(34302-69-7)Computed Properties of C28H26N4O can be used in many types of reactions. And in most cases, this compound has more advantages.
