Synthesis, mol-ecular and crystal structure of [(NH)CSSC(NH)][RuBr]Br·3HO.

The title compound, bis-[di-thio-bis-(formamidinium)] hexa-bromido-ruthenium dibromide trihydrate, [(NH)CSSC(NH)][RuBr]Br·3HO, crystallizes in the ortho-rhom-bic system, space group , = 4. The [RuBr] anionic complex has an octa-hedral structure. The Ru-Br distances fall in the range 2.

Two-dimensional high-throughput on-cell screening of immunoglobulins against broad antigen repertoires.

Identifying high-affinity antibodies in human serum is challenging due to extremely low number of circulating B cells specific to the desired antigens. Delays caused by a lack of information on the immunogenic proteins of viral origin hamper the development of therapeutic antibodies. We propose an efficient approach allowing for enrichment of high-affinity antibodies against pathogen proteins with simultaneous epitope mapping, even in the absence of structural information about the pathogenic immunogens.

Crystal structure and Hirshfeld surface analysis of dimethyl 2-oxo-4-(pyridin-2-yl)-6-(thio-phen-2-yl)cyclo-hex-3-ene-1,3-di-carboxyl-ate.

In the title compound, CHNOS, the cyclo-hexene ring adopts nearly an envelope conformation. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming a three-dimensional network. In addition, C-H⋯π inter-actions connect the mol-ecules by forming layers parallel to the (010) plane.

The asymmetric unit of the title compound, CHN·HO, comproses two mol-ecules ( and ), together with a water mol-ecule. The terminal phenyl groups attached to the methyl groups of the mol-ecules and do not overlap completely, but are approximately perpendicular. In the crystal, the mol-ecules are connected by N-H⋯N, C-H⋯N, O-H⋯N and N-H⋯O hydrogen bonds with each other directly and through water mol-ecules, forming layers parallel to the (001) plane.

In the title compound, CHBrOS, mol-ecules are connected by inter-molecular C-H⋯S hydrogen bonds with (10) ring motifs, forming ribbons along the -axis direction. C-H⋯π inter-actions consolidate the ribbon structure while van der Waals forces between the ribbons ensure the cohesion of the crystal structure. According to a Hirshfeld surface analysis, H⋯H (40.
