This paper presents the one‐pot reaction synthesis of coordination calcium and
strontium compounds [Ca(L)2(H2O)2 1 and Sr(L)2(H2O)2 2] with the 2‐(4‐
chlorophenylamino) benzoic acid ligand (HL = C13H10NO2Cl). The complexes
were obtained in good yields, and their structures were corroborated according
to their CHN, spectroscopic (IR and UV/Vis.) and solution molar conductivity
data as the latter confirmed their molecular nature. Additionally, the powder
X‐ray diffraction pattern of the complexes was used to determine the cell
parameters and the hkl indices together with their corresponding 2θ values.
The microbial resistance against the currently available antifungal agents
requires searching for new antifungal compounds. Promising fungicidal activities
of these coordination complexes were determined against the Fusarium
corn disease as complexes 1 and 2 at 30°C inhibited the grain pathogenicity
by 70% and 66%, respectively. Moreover, 1 and 2 retarded the amylase enzymes
that are responsible for the pathogenicity by 35.13% and 26.22% at 30°C.

3D printing is recognized as a powerful tool to develop complex geometries
for a variety of materials including nanocellulose. Herein, a one-pot synthesis
of 3D printable hydrogel ink containing zeolitic imidazolate frameworks
(ZIF-8) anchored on anionic 2,2,6,6-tetramethylpiperidine-1-oxylradicalmediated oxidized cellulose nanofibers (TOCNF) is presented. The synthesis
approach of ZIF-8@TOCNF (CelloZIF8) hybrid inks is simple, fast (≈30 min),
environmentally friendly, takes place at room temperature, and allows easy
encapsulation of guest molecules such as curcumin. Shear thinning properties of the hybrid hydrogel inks facilitate the 3D printing of porous scaffolds
with excellent shape fidelity. The scaffolds show pH controlled curcumin
release. The synthesis route offers a general approach for metal–organic
frameworks (MOF) processing and is successfully applied to other types of
MOFs such as MIL-100 (Fe) and other guest molecules as methylene blue.
This study may open new venues for MOFs processing and its large-scale
applications.
