In the title complex, {[Cu(C8H12N3O2)(C5H8N)]NO3·H2O}n, the Cu atom is coordinated by two [(3,5‐dimethyl‐1H‐pyrazol‐1‐yl)methyl­amino]acetate anions and one 3,5‐dimethyl‐1H‐pyrazole ligand. There is one nitrate anion and one water mol­ecule in the asymmetric unit. The crystal packing is stabilized by N—H⋯O and O—H⋯O hydrogen bonds.

Auf dem im Reaktionsschema angegebenen Weg werden aus den funktionalisierten Isoxazol‐4‐carbonsäuren (II) und (VII) die im Titel genannten Verbindungen (III) und (VIII) synthetisiert.

The crystal structure determination of the new title spiro­isoxazoline, C24H19NO3S, shows that the five‐membered isoxazoline ring is coplanar with the phenyl ring attached to it. The p‐methoxy­phenyl ring is almost perpendicular to the isoxazoline ring.

The mol­ecule of the title compound, C16H26N6, is located on a crystallographic centre of inversion; as a result, there is just one half‐mol­ecule in the asymmetric unit. The piperazine ring adopts an ideal chair conformation. The substituents at the piperazine N atoms are in equatorial positions.
