In the title compound, [Cu(CH(3)COO)(2)(C(18)H(16)N(2)O(2))]·4H(2)O, the Cu(II) ion is six-coordinated in a Jahn-Teller-distorted octa-hedral geometry environment defined by four O atoms and two N atoms. A chain structure along [100] is built up by inter-molecular O-H⋯O hydrogen bonds involving the uncoordinated water mol-ecules.

A mononuclear square-planar Cu complex of (5-methyl-1-pyrazol-3-yl)carbamate, [Cu(CHNO)]·4HO, was synthesized using a one-pot reaction from 5-methyl-3-pyrazolamine and copper(II) acetate in water under ambient conditions. The adsorption of carbon dioxide from air was facilitated by the addition of di-ethano-lamine to the reaction mixture. While di-ethano-lamine is not a component of the final product, it plays a pivotal role in the reaction by creating an alkaline environment, thereby enabling the adsorption of atmos-pheric carbon dioxide.

Single crystals of three novel transition-metal oxalates, dirubidium di-aqua-dioxalatocobalt(II) dihydrate or dirubidium cobalt(II) bis-(oxalate) tetra-hydrate, Rb[Co(CO)(HO)]·2HO, (I), -poly[dirubidium [[di-chlorido-cobalt(II)]-μ-oxalato]] or dirubidium cobalt(II) dichloride oxalate, {Rb[CoCl(CO)]} , (II), and poly[dipotassium [tri-μ-oxalato-copper(II)dilithium] dihydrate] or dipotassium dilithium copper(II) tris-(oxalate) dihydrate, {K[LiCu(CO)]·2HO} , (III), have been grown under hydro-thermal conditions and their crystal structures determined using single-crystal X-ray diffraction. The structure of (I) exhibits isolated octa-hedral [Co(CO)(HO)] units, whereas (II) consists of chains of Co ions bridged by bidentate oxalato ligands and (III) displays a novel tri-periodic network of Li and Cu ions linked by oxalato bridging ligands.

The dark-red title complex crystallized from an equimolar methanol solution of ()-5-(ethyl-amino)-4-methyl-2-[(pyridin-2-yl)diazen-yl]phenol and CuCl(phen) (phen = 1,10-phenanthroline) as a centrosymmetric dimer, [CuCl(CHNO)]. The Cu atoms are bridged by two Cl ligands and have a slightly distorted square-pyramidal coordination, where two N atoms from the azo and the pyridine moieties, a phenolic O and a Cl atom comprise the base and the other Cl occupies the apex position. The apical Cu-Cl bond, 2.

The title Cu macrocyclic complex salt tetra-hydrate, [Cu(CHNO)](CHO)·4HO, sees the metal atom located on a centre of inversion and coordinated within a 4 + 2 (NO) tetra-gonally distorted coordination geometry; the N atoms are derived from the macrocycle and the O atoms from weakly associated [3.2048 (15) Å] acetate anions. Further stability to the three-ion aggregate is provided by intra-molecular amine-N-H⋯O(carboxyl-ate) hydrogen bonds.
