In the title compound, CHClNO, the two piperidine rings of the di-aza-bicyclo moiety adopt distorted-chair conformations. Inter-molecular C-H⋯π inter-actions are mainly responsible for the crystal packing. The inter-molecular inter-actions were qu-anti-fied and analysed using Hirshfeld surface analysis, revealing that H⋯H inter-actions contribute most to the crystal packing (52.

Spontaneous hemoperitoneum in pregnancy (SHiP), an unprovoked, non-traumatic intraperitoneal bleed in pregnancy and up to 42 days postpartum, is a rare but potentially life-threatening clinical condition. Here, we report a rare case of spontaneous rupture of uterine surface variceal vessels in the second trimester of pregnancy mimicking acute appendicitis that posed diagnostic difficulties and challenges in management.

The congenital anomalies seen in this syndrome vary widely and defects may be isolated or multiple and do not follow a specific pattern. Asymmetric distribution of defects is the hallmark of this syndrome.

Urea tartaric acid (UT) an organic nonlinear optical (NLO) material was synthesized from aqueous solution and the crystals were grown by the slow evaporation technique. The single crystal X-ray diffraction (XRD) analysis revealed that the UT crystal belongs to the orthorhombic system. The functional groups of UT have been identified by the Fourier transform infrared spectral studies.

However, none of the currently available alumina or zirconia based ceramic orthodontic brackets meet the esthetic demands of adult patients. Inherent hexagonal lattice structure and associated birefringence limits the visible light transmission in polycrystalline alumina and make them appear white and non transparent.
