Tetrakis(μ3-9-oxa-10-boraanthracen-10-olato)tetrakis[(diethyl ether)lithium]
The title compound, [Li(4)O(4)(C(12)H(8)BO)(4)(C(4)H(10)O)(4)], features a Li(4)O(4) cube. Each Li atom in the cube is additionally coordinated by a diethyl ether mol-ecule and each O atom in the cube carries a 9-oxa-10-boraanthracene residue. The crystal studied was a non-merohedral twin [twin law (-1 0 0 / 0 0 1 / 0 1 0); the contribution of the major twin component refined to 0.553 (3)] emul...

متن کامل10-Benzyl-10H-phenothiazine 9-oxide
In the title compound, C(19)H(15)NOS, the butterfly angle between the mean planes defined by the S, N and phenyl C atoms of the two wings of the phenothiazine unit is 23.4 (1)°. In the crystal, a supra-molecular two-dimensional arrangement arises from weak inter-molecular C-H⋯O inter-actions.
متن کاملLysine Carboxylation in Proteins: OXA-10 -Lactamase
An increasing number of proteins are being shown to have an N -carboxylated lysine in their structures, a posttranslational modification of proteins that proceeds without the intervention of a specific enzyme. The role of the carboxylated lysine in theseproteins is typically structural (hydrogen bonding or metal coordination). However, carboxylated lysines in the active sites of OXA-10 and OXA-...
