Source of materialThem ixture of Ni(CH 3 COO) 2 ·4H 2 O( 0.125 g, 0.5m mol) and abglyH 2 (N-P-acetamidobenzenesulfonyl-glycine acid, 0.135 g, 0.5 mmol) in 10 ml of 50% methanolic solution was stirred for about 30 minat70°C. Then the pH was adjusted to approximate 7 with 1mol·L -1 NaOH solution, and 5mlof50% methanol solution of 1,10-phenanthroline (0.100 g, 0.5 mmol) was added. The reaction mixture was heated on awater bath for 10 hat70°Cand then filtered.The blue crystal was separated from the mother liquor by slow evaporationatroomtemperatureafter tow weeks (Yield: 0.171 g, 42%).
Experimental detailsThee ffective free volume of thec omplex wasc alculated by PLATON analysis as 21.8%ofthe crystalvolume (397.2 outof the1822.2Å 3 unit cell volume) [9].According to the large U eq of some of the solvate water molecules alower occupancy of some sitescan notberuled out.
DiscussionThe structures and properties of N-protected amino acids has been well researched foralong time due to the presence of R-CONH-R'group analogous to the structure of O-terminalof peptide and proteins [1][2][3][4]. The substitution of an Ar-SO 2 -group at an amine group of amino acids increases the number of coordination donors to three (carboxyl, sulfoxyland amine), which may result in different coordination modes [4,5]. On the other hand, supramolecular networks of higher dimensionalities can be obtained by assembly of coordination polymers with lower dimensionalities via hydrogen-bonding, p···p stacking interactionsorother intermolecular contacts [6,7]. In this paper, we report thes ynthesis and the crystal structure of an ew nickel(II) complex with the (4-acetamidophenyl)sulfonyl)(carboxylatomethyl)amide (abglyH 2 )and 1,10-phenanthroline (phen)ligands. The structure of the title complex [Ni(abgly)(phen) 2 ]·7H 2 Ofeaturesamononuclear motif, which contains one Ni(II) atom, one abgly 2-anion, two chelating phen ligands, and seven solvent water molecules. As shown in the figure, the Ni(II) is slightly dis-Z. Kristallogr.
