A new bi-capped Keggin heteropoly molybdovanadated derivative, [Co (en)3]2[SiMo8V6O42]∙6H2O (1) (en = ethylendiamine) has been hydrothermally synthesized and structurally characterized by the elemental analysis, IR, XPS and single crystal X-ray diffraction. The crystal structure analysis reveals that compound 1 consists of [Co (en)3]2+transition metal coordination fragment and the [SiMo8V6O42]4-building blocks, which are linked together via hydrogen-bonding interactions to form a new 3-D supramolecular networks.

A new tetranuclear complex of zinc(II) with P,P′-diphenylmethylenediphosphinate and 2,2′- bipyridine ligands was synthesized. [(pcp)(2,2′-bipy)Zn (μ3-pcp)Zn (2,2′-bipy)]2 · 6H2O was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and X-ray diffractometry. The structure consists of tetranuclear complexes connected through water hydrogen-bonding interactions in corrugated 2D layers. Two crystallographically independent zinc ions are in a distorted five-coordinate environment, being surrounded by three oxygen atoms of phosphinate groups (from two pcp ligands) and by two bipy nitrogen donors. Of the two independent pcp anions the first one utilizes all of its oxygen donors to coordinate one metal as bidentate and two metal atoms as a monodentate ligand, whereas the second one is only bidentate for one metal atom.

Tube Type

By the reaction of ammonium perchlorate with anion-incorporated bowl-type dodecavanadates, viz. [V12O32(X)]5− [X = N3 − (1), OCN− and NO3 −], tube-type tetradecavanadates, viz. (NH4)7[V14O38(X)] [X = N3 − (2), OCN− (3) and NO3 − (4)] were synthesized. The crystal structures of penta(tetraethylammonium) azidododecavanadate nitromethane monosolvate, (C8H20N)5[V12O32(N3)]·CH3NO2, 1, heptaammonium azidotetradecavanadate dimethyl sulfoxide hexasolvate, (NH4)7[V14O38(N3)]·6C2H6OS, 2, heptaammonium cyanatotetradecavanadate dimethyl sulfoxide hexasolvate, (NH4)7[V14O38(OCN)]·6C2H6OS, 3, and heptaammonium nitratotetradecavanadate dimethyl sulfoxide hexasolvate, (NH4)7[V14O38(NO3)]·6C2H6OS, 4, were determined. The tube consists of two layers of V7 rings with a guest anion at the centre. The distances between the incorporated anions and the nearest V atoms are 3.058 (3), 3.039 (6) and 2.811 (9) Å for 2, 3 and 4, respectively, showing that the incorporated anions are stabilized via noncovalent interactions. Two ammonium cations cap both ends of the tube to stabilize the structures via hydrogen-bonding interactions. Linear OCN− and N3 − anions sit on the twofold rotation axes of the tube frameworks and the triangular plane of the NO3 − anion deviates from the equatorial plane of the tube by ca 30°.
