Comment
=======

An enormous effort has been devoted to the development of new homochiral coordination polymer duo to their the possibility of applications to enantioselective separation, catalytic processes and magneto-optical processes (Kitagawa *et al.*, 2004; Ma *et al.*, 2007; Liu *et al.*, 2008; Gelbrich *et al.*, 2006)). L-tartaric acid, a simple and inexpensive chiral ligand source, was often used to construct novel chiral multifunctional metal-organic frameworks (McCann *et al.*,1997; Zhang *et al.*, 2003). However, only four zinc-tartrate compounds have been reported (Adama *et al.*, 2007; Lin *et al.*, 2009; Liu *et al.*, 2010; Templeton *et al.*, 1985) up to now. We report here the synthesis and crystal structure of the first mixed-ligand zinc(II) complex with tartrate and 1,10-phenanthroline, I, which has a linear chain structure.

The asymmetric unit of I consists of one Zn atom, one L-tartrate dianion, one phenanthroline and six free water molecules, (Fig. 1). The Zn atom is hexacoordinated by four O atoms (Zn-O = 2.046 (2)-2.200 (2)Å) and two N atoms (Zn-N = 2.127 (2)Å and 2.132 (2)Å) forming \[ZnO~4~N~2~\] distorted octahedral geometry with three *trans*-angles form 159.21 (10)° to 160.73 (10)°. The Zn-*O*(hydroxy) and Zn--*O*(carboxylate) distances are typical for Zn-O bonds. The L-tartrate dianion adopts η~4~µ~2~-chelating/bridging mode to extend Zn(C~12~H~8~N~2~)^2+^ to one-dimensional polymeric chain, which is assembled together to genterate a zipper-like double chain through strong π--π packing interactions between parallel phenanthroline aromatic rings with centroid--centroid distances of 3.552 (2)-3.625 (2)Å. The most noteworthy structural feature of I, is the existence of one-dimensional helical chain water cluster (Fig. 2). In crystal achitecture of I, there are six crystllography independent lattice water molecules, which are interconnected by hydrogen bonds forming a right-handed helical chain. The average Ow···Ow distance of 2.79 (2)Å in I is slightly small than the Ow···Ow distance observed in liquid water (2.85 (3)Å). The hydrogen bonding interactions between the Ow atoms from water cluster chains and the tartrate O atoms from one-dimensional double zipper chains with the average Ow···O distance of 2.77 (2)Å lead to the formation of a three-dimensional supramolecular framework of I.

Experimental {#experimental}
============

A mixture of Zn(NO~3~)~2~^.^6H~2~O (298 mg, 1 mmol), L-(+)-tartaric acid (150 mg, 1 mmol) and 1,10-phenanthroline (180 mg, 1 mmol) in H~2~O (12 ml) was placed in a teflon-lined stainless vessel and heated to 413 K for 72 h. Then, the reaction system was cooled to room temperature during 24 h to give rise to colourless crystals, which were collected and washed with water. Yield 0.191 g (38% based on Zn). Analysis calculated for C~16~H~24~N~2~ZnO~12~ (501.76): C 38.30, H 4.82, N 5.58%; found: C 38.06, H 4.71 N 5.49%.

Refinement {#refinement}
==========

H atoms bonded to C atoms were placed at calculated idealized positions using a riding model - C--H = 0.93%A for 1,10-phenanthroline and 0.98%A for L-tartrate, and *U*~iso~(H) = 1.2*U*~eq~(C). Water H atoms were located in a difference Fourier map and refined isotropically, with O--H and H···H distance restraints of 0.85 (1) and 1.37 (1)Å, respectively.

  Geometry. All s.u.\'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.\'s are taken into account individually in the estimation of s.u.\'s in distances, angles and torsion angles; correlations between s.u.\'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.\'s is used for estimating s.u.\'s involving l.s. planes.
  Refinement. Refinement of *F*^2^ against ALL reflections. The weighted *R*-factor *wR* and goodness of fit *S* are based on *F*^2^, conventional *R*-factors *R* are based on *F*, with *F* set to zero for negative *F*^2^. The threshold expression of *F*^2^ \> σ(*F*^2^) is used only for calculating *R*-factors(gt) *etc*. and is not relevant to the choice of reflections for refinement. *R*-factors based on *F*^2^ are statistically about twice as large as those based on *F*, and *R*-factors based on ALL data will be even larger.
