(a) Hydrogen bonding between cis-NiII(hfac)2(H2O)2 com­plexes in VOXRAB. (b) R44(14) hy­dro­gen-bonded rings in TUKPEU. (c) A view of the hy­dro­gen-bond sheet in KUMBEZ. (d) R44(18) hy­dro­gen-bonded rings in ECOJAI. The CIF files deposited in the CSD for structures VOXRAB, KUMBEZ, and TUKPEU do not con­tain displacement ellipsoid information, so the atoms are drawn as fixed size spheres.
