The first homoleptic oxovanadium(IV)–histidine complex {systematic name: [(S*)-α-amino-4-imidazolepropionato-κ3N,N,O][(S*)-α-amino-3-(1H-imidazol-3-ium-5-yl)propionato-κ2N,O]oxovanadium(IV) perchlorate monohydrate}, [VIVO(C6H8N3O2)(C6H9N3O2)]ClO4·H2O, adopts a distorted octahedral structure where one L-histidine ligand coordinates to the vanadium(IV) center in a tridentate fashion as a monoanion and the other in a bidentate fashion leaving a protonated imidazole group as a pendent group.

The cis,syn,cis-tricyclic [2+2]-dimer of cyclooctatetraene, C16H16, crystallizes in space group Pca21 with two molecules in the asymmetric unit. An extensive network of weak C—H
π(C=C) interactions between the two independent molecules, A and B, as well as A
A and B
B interactions, are observed in the supramolecular assembly. The C—H groups point more towards one C atom than to the centre of the C=C bond. Notable among the interactions are bifurcated (cyclobutane)C—H
C=C contacts that span transannularly the eight-membered ring.
