In the crystal structure of the title compound, [Zn(C(6)H(2)O(5))(H(2)O)(3)](n), an infinite chain is formed along [001] by linking of the Zn(H(2)O)(3) entities with one carboxyl-ate group of the furan-2,5-dicarboxyl-ate ligand. Adjacent chains are linked by O(water)-H⋯O hydrogen-bonding inter-actions. The Zn(H(2)O)(3)O(3) polyhedron displays a distorted octa-hedral geometry with one weak Zn-O(carboxyl-ate) coordination [2.433 (8) A°] and two water mol-ecules located in axial positions. Except for one of the axial water molecules and two adjacent H atoms, the other atoms (including H atoms) possess site symmetry m.

The asymmetric unit of the title compound, {[Co(CHO)(HO)]·2CHNO} or {[Co(Hdondc)(HO)]·2DMF} , comprises half of a Co ion, half of a 1,5-di-hydroxy-naphthalene-2,6-di-carboxyl-ate dianion (Hdondc), two water mol-ecules and a di-methyl-formamide (DMF) mol-ecule. The Co ion, which is located on a crystallographic inversion center, exhibits a distorted six-coord-inated octa-hedral geometry with two oxygen atoms of the Hdondc ligand and four oxygen atoms of the water mol-ecules. The carboxyl-ate group is almost coplanar with the naphthalene moiety and shows monodentate coordination to the Co ion.

Reaction of copper(II) bromide with 3,5-di-chloro-pyridine (3,5-Clpy) or 3,5-di-methyl-pyridine (3,5-Mepy) led to the isolation of the coordination polymers -poly[[bis-(3,5-di-chloro-pyridine)-copper(II)]-di-μ-bromido], [CuBr(CHClN)] or [CuBr(3,5-Clpy)] (), and -poly[[bis-(3,5-di-methyl-pyridine)-copper(II)]-di-μ-bromido], [CuBr(CHN)] or [CuBr(3,5-Mepy)] (), respectively. The structures are characterized by bibromide-bridged chains [(av.) = 3.

The asymmetric units of -poly[[(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ , , , )nickel(II)]-μ-sulfato-κ : ], [Ni(SO)(CHN)] (), and -poly[[(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ , , , )nickel(II)]-μ-sul-fato-κ : ] hemi[4,4',4'',4'''-(2,2',4,4',6,6'-hexa-methyl-[1,1'-biphen-yl]-3,3',5,5'-tetra-yl)tetra-benzoic acid] nona-hydrate], {[Ni(SO)(CHN)]·CHO·18HO} (), consist of two crystallographically unique centrosymmetric macrocyclic dications and a sulfate dianion. In it includes additionally a mol-ecule of the undissociated acid (2,2',4,4',6,6'-hexa-meth-yl[1,1'-biphen-yl]-3,3',5,5'-tetra-yl)tetra-(benzoic acid) located on a crystallographic twofold axis and nine highly disordered water mol-ecules of crystallization. In both compounds, the metal ions are coordinated in the equatorial plane by the four secondary N atoms of the macrocyclic ligand, which adopts the most energetic-ally stable -III conformation.

In this study, we present a new N-derivative of L-phenylalanine with 2-naphthaldehyde (PN), obtained by the Schiff base formation procedure and its subsequent reduction. This compound was crystallized as a zwitterion {2-[(naphthalen-2-ylmethyl)azaniumyl]-3-phenylpropanoate, CHNO}, as an anion in a sodium salt (catena-poly[[diaquasodium(I)-di-μ-aqua] 2-[(naphthalen-2-ylmethyl)amino]-3-phenylpropanoate monohydrate], {[Na(HO)](CHNO)·HO}), as a cation in a chloride salt [(1-carboxy-2-phenylethyl)(naphthalen-2-ylmethyl)azanium chloride acetic acid monosolvate, CHNO·Cl·CHCOOH], and additionally acting as a ligand in the pentacoordinated zinc compound aquabis{2-[(naphthalen-2-ylmethyl)amino]-3-phenylpropanoato-κO}zinc(II), [Zn(CHNO)(HO)] or [Zn(PN)(HO)], denoted (PN-Zn), with the amino acid derivative in its carboxylate form.
