The mol-ecular structure of the title complex, [Ag(NO)(CHP)], exhibits a severely distorted tetra-hedral coordination environment around the central Ag atom, comprising one O and three P atoms. Apart from a primary Ag-O coordination of the nitrato ligand of 2.667 (3) Å, a second (weaker) secondary inter-action of the nitrato ligand the other O atom of 3.118 (4) Å is observed. The compound crystallizes with a complete mol-ecule in the asymmetric unit. Weak C-H⋯O inter-actions consolidate the packing.

Reaction of thorium(IV) nitrate with 2-[(4-phenyl-1-1,2,3-triazol-1-yl)meth-yl]pyridine () yielded (H)[Th(NO)] or (CHN)[Th(NO)] (), instead of the expected mixed-ligand complex [Th(NO) ], which was detected in the mass spectrum of . In the structure, the [Th(NO)] anions display an icosa-hedral coordination geometry and are connected by H cations through C-H⋯O hydrogen bonds. The H cations inter-act N-H⋯N hydrogen bonds.

Cobalt complexes exhibit versatile reactivity with nitric oxide (NO), enabling their utilization in applications ranging from homogeneous catalysis to NO-based modulation of biological processes. However, the coordination geometry around the cobalt center is complex, the therapeutic window of NO is narrow, and controlled NO delivery is difficult. To better understand the complexation of cobalt with NO, we prepared four cobalt nitrato complexes and present a structure-property relationship for ultrasound-triggerable NO release.

The structure of the title compound, [CHN)Ag](NO), contains subtle differences in ligand, metal, and counter-anion coordination. One quinoxaline ligand uses one of its quinoxaline N atoms to bond to one silver cation. That silver cation is bound to a second quinoxaline which, in turn, is bound to a second silver atom; thereby using both of its quinoxaline N atoms.
