In the title compound, C(14)H(12)ClNO, the aromatic rings make a dihedral angle of 59.25 (5)°. The methyl group is disordered over two equally occupied positions. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into infinite C(4) chains running along the a axis.

In the structure of the title compound, C(14)H(12)ClNO, the conformations of the N-H and C=O bonds are anti to each other. Furthermore, the conformation of the C=O bond is syn to the meta-methyl group in the benzoyl ring. The central -NH-C(=O)- amido group makes a dihedral angle of 32.4 (1)° with the benzoyl ring and 36.1 (1)° with the anilino ring. The dihedral angle between the two benzene ri...

In the title compound, C(10)H(9)NOS(2), the dihedral angle between the rhodanine (2-thioxo-1,3-thia-zolidin-4-one) and 3-methyl-phenyl rings is 83.30 (3)°. The H atoms of the methyl group are disordered over two set of sites with an occupancy ratio of 0.58 (3):0.42 (3). In the crystal, the mol-ecules inter-act by way of C-H⋯π and C=O⋯π inter-actions.

The title mol-ecule, C(60)H(70)N(2)O(4)Si(8), lies on an inversion center. In the asymmetric unit, one of the phenyl rings is disordered over two sets of sites with refined occupancies 0.58 (2) and 0.42 (2). In addition, in two substitution sites of the terminal dimeth-yl(vin-yl)silyl unit, a methyl group and the vinyl group are disordered over the same site with refined occupancies 0.523 (13) ...

let $r$ be an associative ring with identity. an element $x in r$ is called $mathbb{z}g$-regular (resp. strongly $mathbb{z}g$-regular) if there exist $g in g$, $n in mathbb{z}$ and $r in r$ such that $x^{ng}=x^{ng}rx^{ng}$ (resp. $x^{ng}=x^{(n+1)g}$). a ring $r$ is called $mathbb{z}g$-regular (resp. strongly $mathbb{z}g$-regular) if every element of $r$ is $mathbb{z}g$-regular (resp. strongly $...
