Unsymmetrical Structure

A novel actinide cluster, UNU, is stabilized inside a C80 fullerene cage. The U(iv)NU(v) cluster features two UN bonds with uneven bond distances of 2.058(3) Å and 1.943(3) Å, leading to an unsymmetrical structure.

The Stability

By doing research on the optical characteristics of TFEL panel, a driver circuit controlled by Field-Programmable Gate Array(FPGA) is designed. This design adopts an unsymmetrical way to lighten the panel which is different from the custom symmetrical hybrids. The availability of this unsymmetrical structure improves the stability when the system is on the high-voltage condition, prolongs the service life of the driver circuit, and significantly reduces the costs of a TFEL display system.

Trimethylamine Oxide

The sterically highly shielded and monomeric tetrakis[bis(trimethylsilyl)methyl]dialuminoxane R2Al - O - AlR2 (R = CH(SiMe3)2) 1 forms 1:1 and 1:2 adducts on treatment with trimethylamine oxide. Both products have been characterized by crystal structure determination. Contrary to the linear educt 1, the complexes show bent Al - O - Al groups with bond angles of 162.3 and 161.4°. The mono adduct 2 has three- and four-coordinated Al atoms with a very short Al - O bond between the bridging oxygen and the coordinatively unsaturated Al atom (168.7 pm), possibly indicating a π-interaction. The second bond of the dialuminoxane fragment is lengthened to 175.3 pm and represents a “normal” Al - O distance. The Al - O bond to the amine oxide ligand (184.6 pm) lies within the range o f dative Al - O bonds. As shown by NMR spectroscopy the unsymmetrical structure is preserved in toluene solution up to 90 °C. In the bis(amine-oxide) adduct 3 both A l atoms are four-coordinated with very similar inner Al - O bond lengths o f 173.6 pm.
