In the title compound, C(16)H(19)N(5)·2H(2)O, the triazole ring makes dihedral angles of 70.61 (6) and 41.89 (8)°, respectively, with the imidazole and benzene rings. The water mol-ecules are involved in inter-molecular O-H⋯N and O-H⋯O hydrogen bonds, which stabilize the crystal packing.
In the title compound, C(14)H(17)N(5)S·H(2)O, the triazole ring makes dihedral angles of 48.15 (8) and 84.92 (8)° with the imidazole and thio-phenyl rings, respectively. The water mol-ecule is involved in inter-molecular O-H⋯N hydrogen bonding.
In the title compound, C(14)H(20)N(2)O(3)·H(2)O, the geometry about the morpholine N atom implies sp(3) hybridization. In the crystal, symmetry-related mol-ecules are linked by inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, forming infinite chains along the b axis. The chain structure is further stabilized by intra-molecular C-H⋯O inter-actions.
In the title compound, C(16)H(17)N(3)O(2)S·H(2)O, the triazole ring makes a dihedral angle of 34.63 (6)° with the benzene ring. The thio-phene ring is disordered over two orientations [occupancy ratio = 0.634 (4):0.366 (4)] which make dihedral angles of 54.61 (16) and 54.57 (31)° with the triazole ring. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds(More)
Malignant mixed tumors of salivary gland are extremely rare tumors defined by the presence of malignant epithelial and mesenchymal components together. We report here a case of carcinosarcoma arising from a recurrent pleomorphic adenoma of submandibular salivary gland in a 36 year old woman. Histology showed a monomorphic picture dominated by malignant(More)
