Summary of "How Many Pnicogen Bonds Can Be Formed to a Central Atom Simultaneously?"

A central ZF3 molecule (Z=P, As, Sb, Bi) is allowed to interact with a number of nucleophiles exemplified by NCH, NH3, and NC- anion. The Z⋯N pnicogen bond (ZB) to a single base grows stronger for heavier Z atom: P < A < Sb < Bi, and follows the NCH < NH3 < NC- order for the three bases. The maximum number of ZBs depends on both the nature of the base and pnicogen atom. PF3 and AsF3 can pnicogen bond with only a single CN-; SbF3 and BiF3 can interact with two anions, but only weakly. The weak NCH nucleophile can engage in a maximum of two ZBs, while three ZBs occur for NH3. The latter NH3 maximum can be extended to four ZBs, but only for BiF3. The fourth ZB is somewhat longer and weaker than the others, and the entire (H3N)4···BiF3 complex relies partially on secondary interactions for its stability.

Medical and Biotech [MESH] Definitions

Chemical groups containing the covalent sulfur bonds -S-. The sulfur atom can be bound to inorganic or organic moieties.

Carbon-containing thiophosphonic acid compounds. Included under this heading are compounds that have carbon bound to either SULFUR atom, PHOSPHOROUS atom, or the OXYGEN atom of the SPO2 core structure.

A group of beta-lactam antibiotics in which the sulfur atom in the thiazolidine ring of the penicillin molecule is replaced by a carbon atom. THIENAMYCINS are a subgroup of carbapenems which have a sulfur atom as the first constituent of the side chain.

A reaction characterized by a violet color upon the addition of copper sulfate to all compounds with two amide or peptide bonds linked directly or through an intermediate carbon atom. Used in the detection and estimation of proteins and peptides having more than two amino acids.

The exposure of protein to chemicals, or heat, which disrupt the non-covalent bonds and/or disulfide bonds responsible for maintaining the three-dimensional shape and activity of the native protein, while leaving the peptide bonds intact.
