• Conglomerate crystallization
• Kryptoracemic crystallization
• Unbalanced crystallization

The compound bis(ethylenediamine-N,N')-(oxalato-O,O')-cobalt biphenyl-4,4'-disulfonate hydrate, refcode TIQHOR, crystallizes with four Co(III) cations in the asymmetric unit. Another pair of compounds, rac-bis(ethylenediamine-N,N')-(oxalato-O,O')-cobalt(III) L-hydrogenaspartate, refcode VAGBOU, and tetra-ammine-(N-benzylethanediamine)-cobalt(III) trinitrate sesquihydrate, refcode ZIFHEB crystallize both as conglomerates and kryptoracemates. Their stereochemical characteristics are described, and the fact that they display more than one mode of crystallization in a single lattice, is illustrated numerically and visually.
