چکیده
In the racemic title compound, C(14)H(11)N(3)O(3), the pyrimidine ring has an envelope conformation with the puckering parameters Q = 0.3338 (17) Å, Θ = 60.1 (3) and ϕ = 290.4 (3)°. The two N-H groups form hydrogen bonds with symmetry-related mol-ecules, building a two-dimensional network parallel to the (10) plane.

Redetermination at 113 K of 2,2-tetramethylene-1,2-dihydroquinazolin-4(3H)-one
The title compound {systematic name: spiro-[cyclo-pentane-1,2'(1'H)-quinazolin]-4'(3'H)-one]}, C(12)H(14)N(2)O, has been reported previously [Klemm, Weakley, Gilbertson & Song (1998 ▶). J. Heterocycl Chem. 35, 1269-1273]. Its structure has been redetermined at 113 K with greater precision for all data. The mol-ecule is built up from two fused six-membered rings and one five-membered ring linked...

In the mol-ecule of the title compound, C(15)H(14)N(2)O, the six-membered 1,3-diaza ring assumes an envelope conformation. The two benzene ring planes are almost perpendicular to each other, making a dihedral angle of 85.53 (5)°. Supra-molecular aggregation is mainly effected by N-H⋯O hydrogen bonding.

The asymmetric unit of the title compound, C(14)H(11)BrN(2)O(2), contains two independent mol-ecules connected into a dimer by inter-molecular N-H⋯O hydrogen bonds involving the amine and carbonyl groups. The dimers are further connected by O-H⋯O hydrogen bonds, forming chains running parallel to the a axis, which are stabilized through π-π stacking inter-actions, with a centroid-centroid dista...

The methanol solven...
متن کاملIsolation, observation, and computational modeling of proposed intermediates in catalytic proton reductions with the hydrogenase mimic Fe2(CO)6S2C6H4.
Proposed electrocatalytic proton reduction intermediates of hydrogenase mimics were synthesized, observed, and studied computationally. A new mechanism for H(2) generation appears to involve Fe(2)(CO)(6)(1,2-S(2)C(6)H(4)) (3), the dianions {[1,2-S(2)C(6)H(4)][Fe(CO)(3)(μ-CO)Fe(CO)(2)](2-) (3(2-)), the bridging hydride {[1,2-S(2)C(6)H(4)][Fe(CO)(3)(μ-CO)(μ-H)Fe(CO)(2)]}(-), 3H(-)(bridging), and ...
