چکیده
The asymmetric unit of the title compound, C16H13N3O3·0.5C2H6OS, is composed of two independent pyrazolidine-3,5-dione mol-ecules and one dimethyl sulfoxide solvent mol-ecule. In each pyrazolidine-3,5-dione mol-ecule, an intra-molecular N-H⋯O hydrogen bond forms an S(5)S(6) motif. In the crystal, pairs of each independent pyrazolidine-3,5-dione mol-ecule are linked by N-H⋯O hydrogen bonds, forming dimers with R 2 (2)(8) motifs. These dimers are connected with the other mol-ecules through the solvent mol-ecules via O-H⋯O hydrogen bonds, forming ribbons along the b-axis direction. C-H⋯π inter-actions connect the ribbons. C-H⋯O interactions also occur.

In the title compound, C13H13N3O3, the pyrazolidine ring adopts a shallow envelope conformation, with the carbonyl C atom closest to the benzene ring as the flap [deviation of 0.126 (1) Å from the plane through the remaining atoms (r.m.s. deviation = 0.011 Å)]. The dihedral angle between the pyrazolidine ring (all atoms) and the benzene ring is 51.09 (4)°. An extremely short (2.08 Å) intra-mole...

The Mo(VI) atom in the title complex, [Mo(C(11)H(13)N(3)OS)O(2)(C(2)H(6)OS)], is N,N',O-coordinated by the dianionic tridentate ligand, two mutually cis oxide O atoms and a dimethyl sulfoxide O atom, defining a distorted octa-hedral N(2)O(4) donor set. The most prominent feature of the crystal packing is the formation of inversion dimers via pairs of N-H⋯O hydrogen bonds and eight-membered {⋯HN...

The title Schiff base compound, C(23)H(23)N(5)O, was synthesized by the reaction of 4-amino-phenazone and 3,5-dimethyl-1-phenyl-pyrazole-4-carbaxaldehyde. The mol-ecule adopts an E configuration about the central C=N double bond. A weak intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The dihedral angle between the pyrazole rings is 24.72 (10)° and the dihedral angles between t...

In the title mononuclear complex, [Sn(CH(3))(3)(C(7)H(5)N(2)O(6))(C(2)H(6)OS)], the Sn(IV) ion is coordinated by three methyl groups in the equatorial plane, and by an O atom from a 2-methyl-3,5-dinitrobenzoate ligand and a dimethyl sulfoxide ligand in the axial sites, to form a slightly distorted trigonal-bipyramidal environment. The O atoms of one of the nitro groups are disordered over two s...
