چکیده
The mol-ecule of the title compound, C(35)H(27)N(3)O(2), lies on a twofold rotation axis passing through the pyridine ring. The five-membered ring is approximately flat (r.m.s. deviation = 0.065 Å) and is essentially coplanar [dihedral angle = 4.2 (2)°] with the pyridine ring.

The title compound,[FeCl2(C18H25N3O2)], has a distorted tetra-hedral Cl2N2 coordination of the Fe(II) atom as a result of the constraints imposed by the 2-[2,2-bis-(4,4-dimethyl-4,5-di-hydro-1,3-oxazol-2-yl)prop-yl]pyridine ligand. The pyridine ring is almost perpendicular to the six-membered chelated ring containing the metal atom [dihedral angle between their mean planes = 88.5 (1)°].

The commercially available title compound, C(25)H(23)N(3)O(2), has been known since 1993 [Nesper et al. (1993 ▶). Helv. Chim. Acta, 76, 2239-2249], but has not been structurally characterized until now. In the free ligand, the N atoms of both oxazoline rings point in opposite directions. The phenyl rings make dihedral angles of 30.56 (5) and 84.57 (3)° with the pyridine ring and 72.85 (3)° with...

In the title compound, C25H25NO2, the phenyl ring on the 1,3-oxazole ring is disordered over two positions with occupancies of 0.600 (4) and 0.400 (4). The inter-planar angle between these two disordered rings is 77.8 (2)°. There is an intra-molecular O-H⋯N hydrogen bond of moderate strength. In the crystal, C-H⋯π inter-actions interconnect neighbouring molecules. The absolute structure has bee...

The title tetra-nuclear Cu(II) complex, [Cu(4)(C(12)H(12)N(2)O(2))(4)(CH(3)O)(4)(ClO(4))(2)](ClO(4))(2), is located around an inversion center. Each Cu(II) atom is coordinated by two cis-O atoms from two bridging methano-late anions and two cis-N atoms from two bridging 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in the basal plane, and is further coordinated by one O atom of the b...
