“…The phenomenon of SCSC transformation has been noticed long ago, and since then it has drawn great attention and has been extended to many other complexes as well. − In many complexes SCSC transformation is facilitated by a change in color of the crystals which makes them a potential candidate for sensor technology. − SCSC transformation is the process where a single crystal is exposed to solvent vapors, heat, and light and sometimes by applying mechanochemical forces, resulting in structurally transformed products (Figure ). − In general, exposing single crystals to external forces results in the loss of single crystallinity .…”

The present review focuses on the solid state structural transformations in discrete molecules. Since the molecules in the crystal lattice are closely packed, any transformation in the solid state is difficult due to restricted movement of the molecules. These transformations can be triggered by external stimuli, such as light, heat, uptake or exchange of solvent, mechanochemical force, etc. which may be observed by a change in their physical properties like color, magnetism, porosity, and optical. Single-crystal-to-single-crystal (SCSC) transformations in metal−organic frameworks and coordination polymers are well documented; however, reports on SCSC transformations at the discrete molecular level still remain scarce. In this review, we have compiled some interesting examples from the literature on SCSC transformation at the discrete molecular level using various external stimuli.

“…The guest species like solvents, ions, or confined organic molecules accommodated in the pores can act as templates and determine the shapes and sizes of pores [8,9]. Alongside the rigid 3D Metal-Organic Frameworks (MOFs), impressive adsorption properties accompanied by the guest selectivity were reported for 1D and 2D coordination networks [10][11][12].…”

Eight mixed-ligand coordination networks, [Cd(2-aba)(NO3)(4-bphz)3/2]n·n(dmf) (1), [Cd(2-aba)2(4-bphz)]n·0.75n(dmf) (2), [Cd(seb)(4-bphz)]n·n(H2O) (3), [Cd(seb)(4-bpmhz)]n·n(H2O) (4), [Cd(hpa)(3-bphz)]n (5), [Zn(1,3-bdc)(3-bpmhz)]n·n(MeOH) (6), [Cd(1,3-bdc)(3-bpmhz)]n ·0.5n(H2O)·0.5n(EtOH) (7), and [Cd(NO3)2(3-bphz)(bpe)]n·n(3-bphz) (8) were obtained by interplay of cadmium nitrate tetrahydrate or zinc nitrate hexahydrate with 2-aminobenzenecarboxylic acid (H(2-aba)), three dicarboxylic acids, sebacic (decanedioic acid, H2seb), homophthalic (2-(carboxymethyl)benzoic acid, H2hpa), isophthalic (1,3-benzenedicarboxylic acid, H2(1,3-bdc)) acids, bis(4-pyridyl)ethane (bpe) and with four azine ligands, 1,2-bis(pyridin-4-ylmethylene)hydrazine (4-bphz), 1,2-bis(1-(pyridin-4-yl)ethylidene) hydrazine (4-bpmhz), 1,2-bis(pyridin-3-ylmethylene)hydrazine (3-bphz), and 1,2-bis(1-(pyridin-3-yl) ethylidene)hydrazine (3-bpmhz). Compounds 1 and 2 are 1D coordination polymers, while compounds 3–8 are 2D coordination polymers. All compounds were characterized by spectroscopic and X-ray diffraction methods of analysis. The solvent uptakes and stabilities to the guest evacuation were studied and compared for 1D and 2D coordination networks. The de-solvated forms revealed a significant increase of emission in comparison with the as-synthesized crystals.

“…Various strategies for the rational design of coordination polymers (CPs) or metalorganic frameworks (MOFs) have received considerable attention recently, not only because of their structural diversities and intriguing topologies [1][2][3][4][5][6], but also due to potential applications in the fields of gas storage, separation, fluorescence, drug delivery, and related fields [712]. The creation of desirable CPs or MOFs with variable dimensions relies on the control of a few critical factors, such as functionality on the ligand, concentration, template, pH, temperature, the solvent system, and reaction time, among others [13][14][15][16][17].…”

A discrete complex [Zn(tpro) 2 (H 2 O) 2 ] (1, Htpro = L-thioproline), and two structural isomers of coordination polymers, a 1D chain of [Zn(tpro) 2 ] n (2) and a layer structure of [Zn(tpro) 2 ] n (3), have been synthesized and characterized. The discrete complex 1 undergoes a single-crystal to single-crystal temperature-driven structural transformation, leading to a 1D helical coordination polymer 2. Compound 3 has a 2D homochiral layer network with a (4,4) topology. These layers are mutually linked through hydrogen bonding interactions, resulting in the formation of a 3D network. When 1 was heated, it undergoes almost completely conversion to the microcrystalline of compound 2, which was confirmed by powder X-ray diffractions (PXRD). After removing the coordinated water molecules by heating at temperature of up to 150 C, the carboxylate motifs could be activated and their orientations became distorted, after which, they attacked the activation sites of the Zn(II) centers, leading to a the formation of a 1D helix. Moreover, a portion of the PXRD pattern of 3 was converted into a pattern for 2, and the ratio between 2 and 3 was precisely determined by the simulating study of the synchrotron in situ PXRD patterns. Consequently, such a 0D complex is capable of underdoing single-crystal to single-crystal transformations and can be converted into 1D and/or 2D amino acid-based coordination polymers.
