“…This type of structure forms with a wide range of guests, including p - and m -xylenes, methanol, p -cymene, 4-MePy, and others . This structure is also formed by other similar complexes, including [M(4-MePy) 4 (NCS) 2 ] with Mg(II), , Fe(II), , Co(II), , and Zn(II) 25 as M, [M(4-vinylpyridine) 4 (NCS) 2 ] with Co(II) and Ni(II), and [Ni(4-ethylpyridine) 4 (NCS) 2 ]. − A remarkable property of β-phases of the title complex and some of its analogues is that they survive total guest removal, producing empty microporous β-polymorphs.…”

The inclusion chemistry of the title complex was revisited in the context of three topical problems of present-day crystal engineering: conventional and pseudo-polymorphism, the design of organic zeolite mimics, and the creation of "third generation" porous metal-organic frameworks. The crystal structures of dense (R) and microporous (β) polymorphs of the complex were redetermined and two new crystal structures were studied: β-and γ-inclusion phases of the complex (1:1 and 1:2 host-to-guest ratio, respectively) with benzene as the simplest aromatic guest. Although both the β-and γ-crystal architectures display a remarkable adaptability toward inclusion of various guests, the mechanisms of this adaptability are essentially different. The microporous β-phase is capable of expanding by 14.5% in response to the size of the included guest or variations in temperature. This flexibility is the highest ever observed for a metal-organic microporous framework and is responsible for the zeolitic behavior of the material. In contrast, the γ-phase shows an ability to transform to a number of architectures that are topologically similar but crystallographically different.
