The parent bispidine absorbs 2 HCl; the solid forms a supramolecular structure in which different sheets of parallel chains are stacked crosswise to one another.

The N-allyl groups of N,N′-diallyl-bispidine metal complexes allow grafting on polyester fibers; thus, the metal complexes become immobilized an can be used as heterogeneous catalysts.
Bispidine represents a plastic crystal (phase I) in which the molecules spin on their positions in the lattice. Nevertheless, the ordered structure (phase II) has been determined in which the proton-sponge-like diamine bites its own NH proton.
This Ni(0) complex having a trisubstituted macrocyclic 1,6-dien-11-yne ligand looks like a chair in which two substituents represent the front legs and the third one forms the back rest.
Two 4-oxopiperidinium cations are associated to one another to form a dicationic species. The ammonium protons engage in hydrogen bonds to diethyl ether.
In (bispidine)PtCl2 (a cisplatin-type compound) the complex molecules are linked by parallel N–H×××Cl hydrogen bonds to give infinite bands, which are festooned on both sides by strings of water molecules.
For carboplatin derivatives it is geometrically difficult to associate by hydrogen bonding. Therefore, these complexes become fully solvated by a hydrate shell, which enhances water solubility.
In Cs[H2NB2(C6F5)6] the cesium cation features a Cs+F16 environment, corresponding to a record-setting coordination number CN = 16. By interacting with 16×2 electrons 55Cs+ formally assumes the closed-shell electronic configuration of the noble gas 86Rn.
The salts M[B(C6F5)4] (M = Rb, Cs, Tl) form isomorphous 3D networks, giving rise to water-insoluble crystalline solids. Remarkably enough, the complexes represent the first examples of CN = 15 in a defined molecular compound and for a donor atom other than H.
(C7H14N2)PtCl2×3H2O consists of polymeric chains of (C7H14N2)PtCl2 molecules, associated to one another by strong NH×××Cl hydrogen bonds. The chains are festooned by independent chains of water molecules in a lasagna-type structure. H-bonding is an important issue for cisplatin-type drugs.

Quite rare – the imidazole ligand and the hydride at nickel lie in the same plane, actually a mirror plane.
