{Fe}_{4} {Si}_{2} {Sn}_{7} O_{16}

hosts an undistorted kagome lattice of

{Fe}^{2 +}

(

3 d^{6}, S = 2

) ions. We present results of bulk magnetization and Sn nuclear magnetic resonance (NMR) measurements on an oriented

{Fe}_{4} {Si}_{2} {Sn}_{7} O_{16}

powder sample oriented in geometries parallel (

∥

) and perpendicular (

⊥

) to the external applied magnetic field used for orienting the powder (

B_{ori}

). The bulk susceptibility

χ

shows a broad peak at

T_{N} \sim 3

K associated with antiferromagnetic ordering. NMR spectra indicate the presence of planar anisotropy in the kagome planes. From an analysis of the static NMR shift (

K

) and dynamic spin-lattice relaxation rate (

1 / T_{1}

) we conclude the presence of dominant magnetic fluctuations in the kagome planes. For the

∥

orientation,

K

scales linearly with the bulk susceptibility for temperatures down to

\sim 4

K, while in the

⊥

orientation

K

starts to deviate strongly below

T \sim 30

K. We associate this deviation with the onset of spin-tilting towards the kagome planes. These correlations are also reflected in the

1 / T_{1}

data for the

∥

orientation, which starts to decrease below

T \sim 30

K. In this correlated regime,

T_{N} < T < \sim 30

K, we discuss the formation of positive chiral spin correlations in the kagome planes.
