In the title mol-ecule, CHClNO, the meth-oxy group lies very close to the plane of the phenyl ring while the acetamido group is twisted out of this plane by 28.87 (5)°. In the crystal, a three-dimensional structure is generated by N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds plus C-H⋯π(ring) inter-actions. A Hirshfeld surface analysis of the inter-molecular inter-actions was performed and indicated that C⋯H/H⋯C inter-actions make the largest contribution to the surface area (33.4%).

The synthesis of -tetrakis(3,4,5-trimethoxyphenyl)porphyrin [HT(3,4,5-OCH)PP] and cobalt(II) -tetrakis(3,4,5-trimethoxyphenyl)porphyrin [Co(T(3,4,5-OCH)PP)] has been successfully accomplished. The oxidation properties of [Co(T(3,4,5-OCH)PP)] have been assessed through UV-vis, NMR, and EPR techniques. It can be seen in the UV-vis spectrum that adding SbCl caused extra peaks to appear at 674 nm, which means that a π-cation radical was formed.

The title complex, [Ca(NO)(CHNO)(HO)], crystallizes with an eight-coordinate Ca ion in a distorted trigonal-dodeca-hedral coordination environment. The metal ion is coordinated to two nicotinamide ligands their carbonyl O atoms, two bidentate nitrate anions and two water mol-ecules. The nicotinamide ligands adopt a nearly geometry, while the nitrate anions and aqua ligands are arranged in a pseudo- fashion.

In the title salt, NH ·[B(CHO)], the boron atom is chelated by two malonate ligands in a bidentate fashion, resulting in a BO tetra-hedron with both chelate rings adopting shallow boat conformations. The extended structure features five N-H⋯O and three C-H⋯O hydrogen bonds, accounting for approximately 69.9% of the total inter-molecular inter-actions.

The conformation of the title mol-ecule, CHClNO, is maintained by intra-molecular N-H⋯O, C-H⋯O, and C-H⋯Cl inter-actions, creating (6), (5), and (6) motifs, respectively. In the crystal, inter-molecular N-H⋯O, C-H⋯O, and C-H⋯Cl inter-actions connect the mol-ecules, forming a three-dimensional network. Additionally, the mol-ecules are linked by C-H⋯π inter-actions, forming layers parallel to the (002) plane.

The mol-ecular conformation of the title compound, CHNO·CHNO, is consolidated by intra-molecular C-H⋯O O-H⋯O hydrogen bonds, forming an (6) ring motif. In the crystal, the mol-ecules are connected by C-H⋯O hydrogen bonds, forming layers parallel to the (101) plane. Furthermore, the mol-ecules form layers parallel to the (102) plane by C-H⋯π inter-actions.
