First Results from BESIII

We present the most recent results from the BESIII experiment. This review covers the studies of charmonium decays, light hadron spectroscopy and charm physics. Especially, the prospects for weak decays of charm mesons are addressed at the BESIII.Comment: Presented at Flavor Physics and CP Violation - FPCP 2010, Turin, Italy, May 25-29, 201

4-{2-[(3,4-Dichloro­phen­yl)(meth­yl)amino]-4-methyl-1,3-thia­zol-5-yl}-N-(3-methyl­phen­yl)pyrimidin-2-amine

In the title compound, C22H19Cl2N5S, the thia­zole and pyrimidine rings are almost co-planar, making a dihedral angle of 6.48 (7)°. In the crystal, intermolecular N—H⋯N hydrogen bonds link pairs of molecules into centrosymmetric dimers.

N-(3-Meth­oxy­phen­yl)-4-{4-methyl-2-[(meth­yl)(4-methyl­phen­yl)amino]-1,3-thia­zol-5-yl}pyrimidin-2-amine

The asymmetric unit of the title compound, C23H23N5OS, contains two independent mol­ecules. In one mol­ecule, the thia­zole and pyrimidine rings are almost co-planar, making a dihedral angle of 2.48 (8)°. In the other mol­ecule, the corresponding dihedral angle is 12.82 (8)°. The crystal structure is stabilized by weak inter­molecular N—H⋯N and C—H⋯O inter­actions that extend along the b axis
