The title compound, C(5)H(13)NO, is an aliphatic amino-alcohol with both functional groups residing on terminal C atoms. Apart from the hy-droxy group, all non-H atoms are nearly co-planar, the maximum deviation of an atom taking part in the least-squares plane defined by the mentioned non-H atoms being 0.029 (1) Å. In the crystal, O-H⋯N and N-H⋯O hydrogen bonds connect the mol-ecules, forming ...

The asymmetric unit of the title compound, C(6)H(7)NO(3), contains two mol-ecules (A and B) related by a non-crystallographic twofold pseudo-axis. The mol-ecules are joined in the (AABB)(n) manner by O-H⋯O hydrogen bonds between their hy-droxy groups, thus forming C(2) chains along the a-axis direction. Neighboring mol-ecules of the same kind (A and A, or B and B) are related by inversion cente...

In the title compound, C(11)H(19)N(3)O(5), the six-membered ring displays a half-chair conformation and the imidazolidine ring is essentially planar (r.m.s. deviation = 0.088 Å). An inter-molecular hydrogen bond between the hy-droxy O atom and a nitro O atom stabilizes the crystal packing.

We report the identification, in an Extreme Ultraviolet Explorer (EUVE) spectrum, of a hot white dwarf companion to the 3rd magnitude late-B star θ Hya (HR3665, HD79469). This is the second B star+white dwarf binary to be conclusively identified; Vennes et al. (1997), and Burleigh & Barstow (1998) had previously reported the spectroscopic discovery of a hot white dwarf companion to the B5V star...

Let M be a compact simply connected hy-perkk ahler (or holomorphically symplectic) manifold, dim H 2 (M) = n. Assume that M is not a product of hyperkk ahler manifolds. We prove that the Lie algebra

The asymmetric unit of the title compound, C(18)H(18)N(2)O(2), contains three independent mol-ecules. In each, the seven-membered diazepine ring adopts a boat conformation with the hy-droxy-substituted C atom at the prow and fused-ring C atoms at the stern. In the crystal, the mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds. The allyl group of one mol-ecule is equally disordered over tw...

In the title mol-ecule, C(13)H(12)ClNO, the two benzene rings are twisted from each other by a dihedral angle of 68.60 (8)°. In the crystal structure, the hy-droxy and amino H atoms are involved in inter-molecular hydrogen bonds, O-H⋯N and N-H⋯O, respectively, resulting in R(4) (4)(8) loops about inversion centers.
